Morris (Errortale Nice Cream Guy) Identified by their neon purple (and occasionally green) aesthetic, Morris bitties are often genuinely warm and friendly. Like other Nicebitties, they enjoy being able to sell their wares though have been known to get stuck in advertising loops where they repeat the same phrase over and over about buying their ice cream unless snapped out of it. They are well-meaning despite their goods often corrupting whoever eats them, albeit with the exception of their fellow Errortale bitties, and are always remorseful and quick to help reverse the effects when they realize what has happened. Morris types have very little control over their glitching and their body shape and facial features can suddenly change or become twisted at the drop of a hat, sometimes giving them unnerving or even downright terrifying appearances. In terms of clothing they often prefer brightly colored outfits, often with a wide variety of patterns.

Overwrite (Errortale Goner Kid) These unusual bitties are not naturally occurring as they are Mini Monster Kids who have become corrupted in some form. They are often prone to tears and excessive glitching, but can be stabilized as long as they have someone they trust with them (though emotional support dog monster bitties also help greatly, and it is usually recommended that one is adopted with them). Overwrites usually come about due to severe mistreatment or a Mini Monster Kid getting lost and unable to find help. Overwrites can and often do have traits of the MMKs they used to be, though they are primarily gray in color. Though they can be given colorful clothing, these articles will also bleed to gray after a time. Overwrite types also tend to have auditory hallucinations, usually involving hearing their former type name called or whispers that they can't quite make out (although this can vary widely). They not only get quite lethargic in the cold but will glitch more often, and as such require heat lamps to stay stable.

Meissa (Outertale Mettaton) Unquestionably the most dazzling stars in the galaxy (according to their own humble and completely unbiased opinions), Meissa bitties are identified by their navy blue and golden color scheme along with the colorful capes they wear to accentuate their looks. Naturally they gravitate towards star designs that not only feature on their body but in their dual-colored navy and golden hair as well. They have a flair for drama and put their all into everything they do, though like many Mettaminis they tend to be somewhat self-absorbed and don't always treat others well if it doesn't benefit them to some degree. Because of this it's not always easy for them to keep friendships or even familial bonds, though with plenty of reminders that they can't just drop people when it suits them to do so Meissa bitties can be convinced to put more effort into their relationships. These types usually prefer he/him pronouns.

Banana Cream (Underpie Goner Kid) Leaning more towards yellowish-white than gray in terms of coloration, Banana Cream smells as sweet as the banana cream pie that is their namesake. Though they can't bake their signature dish as well as others, they are more than happy to gather ingredients and teach others how to make it even if they can't quite do it themselves. They also tend towards being a little more cheerful, though by no means are they optimistic, than the majority of their fellow Goner Bitties; they're just prone to smiling a little more often, and having a little more energy. In terms of hobbies, they enjoy reading quietly or being read to. They also enjoy watching playthroughs of relaxing games such as Animal Crossing and Stardew Valley.

Spinefoot (Undersplash Nice Cream Guy) Spinefoot bitties, though they often prefer to go by the nickname 'Spiny' or even just 'Rabbit,' live up to their name in that they are unquestionably aquatic rabbits. Their fins are a lighter blue than their fur and tipped with white, and their fingers and toes are webbed. They make and sell Kelp Creams, and they need a steady supply of seaweed in order to make them. Though they prefer to use kelp, they will also accept different types of seaweeds such as dulse and spirulina. They are also not opposed to sharing their stash of seaweed or making different sorts of seaweed-based snacks if it is requested. Though like the other Undersplash bitties they cannot speak English, they can understand it perfectly.

Black Forest (Cakerune Ralsei) These Ralslight bitties love making cakes the most out of all of their fellow Ralslights, but though they are cake experts their favorite is that which gave them their namesake and they smell just as sweet. They are also warm to the touch regardless of the weather, which make this particular type excellent cuddle buddies. As with other Ralslights, they are quite clingy towards their adopters but are also very open-hearted, willing to at least try to get along with any type of bitty. They are especially skilled in healing magic and this transfers into their baking ability, allowing them to make magical food that can heal a large amount if not completely rid the injured party of all damage. Though kind, if someone proves too cruel then they will fight back to protect those they care about.

Shift (Outertale Napstablook) This subspecies is unusually calm, even for a bittyblook, with hardly anything seeming to make them upset or cry. This is because they tend to be better at bottling up their own emotions and feelings so as not to bother others with their so-called 'useless sentimentality.' They tend to be quite slow to open up to others almost as much as typical Underfell bitties, and most if not all of them have a love of listening to or creating space ambient music. Though they act as though they prefer to be alone, the truth is anything but. And as with many other bittyblook types, they enjoy lying on the floor - or the nearest flat surface - and feeling like garbage. It's not uncommon to find they've fallen asleep during this activity, much more so than their other counterparts. They have the tendency to stay up late at night to watch the stars, which might play into their sleeping habits.

Tantan (Caketale Grillby) Grillbitties are experts when it comes to food, and Tantan bitties are no exception. However, they can be perfectionistic about the whole thing. If a Tantan bitty is making constant mistakes, then it's a sure sign that either they are either sick or otherwise have something bothering them. Tantan bitties also have the unfortunate habit of biting off more than they can chew, though it's primarily due to the fact that they have a hard time saying no to anyone and have a soft spot for children. Tantans are about as talkative as your average Grillbitty, though they are a good deal more emotive - perhaps not to the level of an Amber bitty, but emotive nonetheless. They're prone to stress-cooking, but unfortunately this tends to only exacerbate the issue due to the higher likelihood of them making mistakes. Their specialty dish is tangerine cake, and they smell like said treat as well.

Currant (Underpie River Person) If Riverbitties are cryptic, then the Currant type is downright nonsensical. They'll use phrases like 'a cup of grapefruit slices' when describing a spoonful of butter, and should they be corrected they'll typically respond with annoyance. It takes a patient adopter to parse out their unusual language because it does in fact seem to be unique to each Currant bitty and yet somehow if two Currant bitties are put together they can understand one another perfectly even if they might leave others scratching their heads in confusion. Their robe is purplish-black, similar to the fruit that they are named for, and to no one's surprise their favorite snack is black currant pie. Currant bitties also have the unusual habit of staring at people for an uncomfortably long time, almost as if entranced. When they act this way, a gentle poke or calling their name is usually enough to snap them out of it.

Auroris (Outertale Grillby) (inspired by le-poofe's Outertale Grillby) This Grillbitty type tends to lean more on the gentle side and tends to be rather soft-spoken, with a voice barely above a whisper when they speak. Don't mistake their gentleness for weakness though, Auroris bitties are very protective of those they care about and are capable of defending them should the need arise. Though they are normally not very talkative, they do tend to open up around Sans-type bitties and become a bit more talkative. When flustered, an Auroris bitty will turn a rich purple color. They will also occasionally drop astronomy-related puns to lighten the mood, albeit not quite as often as a Sans-type bitty might. Auroris bitties also make for good bedtime companions, given their ability to change color.

Lunar (Outertale Nice Cream Guy) A purveyor of bitty-sized Star Creams of varying flavors, Lunars are a cheerful but not very business-savvy group of rabbits. They are, however, quite empathetic and can pick up on small social cues that others might miss. Lunar bitties also have some medical knowledge and can usually identify illnesses easily, as well as what medicine would be best for treating them. They have excellent bedside manner and don't mind getting sick themselves as long as they can help someone get better and they make an excellent roasted carrot soup. Closer inspection of Lunar bitties makes it seem like someone's thrown glitter into their fur as it sparkles slightly in the right lighting thanks to the stardust that they're usually covered in.

Estelle (Outerrune Noelle) While quite book-smart and good at memorization, Estelle bitties don't quite have as much in the way of street smarts. They tend to have very sheltered outlooks on things and, while willing to help others when they can, are easily overwhelmed with anxiety when thrust into a situation that puts them on the spot. Like other Micro Deer, they do their best to be nice to everyone, including but not limited to social pariahs and bullies though it might get them hurt. They love reading romance novels when they get the time and tend to be hopeless romantics themselves a good majority of the time. Despite this, they lack confidence to stand up to others and shy away from potential conflict despite some weak attempts to intervene.
