Meet Conductor Candy and Eye of Nodus (or just Node)!

My vision of them (since Animation Versus has yet to come out and we don't know enough of these two) is that they're both immortal beings with Candy originally a mortal part of a digital world before her "canon death" (bc Candy was originally part of a story and she was a background character) but Node interfered and IT gave Candy the same immortality IT has whilst erasing the original story/world that Candy originated from.

They're at odds but mostly one sided as Candy holds a grudge at Node for what IT did and "cursing Candy" but Node sees it as saving Candy from an "undeserving fate" and Node is infatuated with Candy due to Candy's natural kindness. (Candy's last gift to IT before the "canon death" was a faux-train ticket for Node. Hence Node has a pale train ticket on ITs armor)

Instant Health potions leave scars, Regen potions don't

Creepers, Endermans and Wardens can purr, but only do when players aren't around. Red has heard them all purr bc of Monster School (all the other Mobs have accepted him in the end, especially after he was one of the people who saved Minecraft)

Creepers feel like moss to the touch

Piglins have an amazing memory since a young age. If you hurt them in any way, they will remember. Same if you help them (like in Blue's case)

Strength potions can leave you feeling dizzy when they wear off. The longer their duration, the higher the chance to feel dizzy in the end

The obsidian pillars in the end are weirdly warm to the touch. That's because of the crystals on top of them. When the crystals are broken, the obsidian immediately cools off

This one is specifically for potions!

Different potions give different side-effects if overused

Strength, ironically, makes you feel weaker when it wears off as the body gets used to it. It also makes you cramp more easily.

Swiftness gives you vertigo and you get sore

It takes you longer to heal from even normal bruises after you drink too many Regeneration potions, as your body gets less used to its normal healing speed

You get really sensible to light after one too many Night Vision potions

Both Leaping and Slow Falling make you lightheaded more easily, and you tend to forget that you aren't using them. Your legs also get more brittle and weak.

Not only Healing can be dangerous (it heals things as they are, meaning that, for example, a bone can be healed wrong), but it also makes you feel weak and can give chronic pain.

Fire Resistance gives you numbness to high temperatures, so you don't really realise if you're burning.

For some reason, Invisibility can cause fainting spells. It also causes temporary blindness.

Water Breathing causes you to easily dehydrate, and it also causes coughing fits.

You get really disoriented with Slowness potions.

Turtle Master can make you disoriented, and it has been known to cause fevers.

Poison leaves you sickly for a very long time (it ranges between a week and two months, depending on how strong the potion was)

You get prone to vomiting and get sick with the potion of Oozing.

Infestation makes you paranoid and hallucinate.

Harming makes your skin more fragile, making cuts an easy thing to get.

Weakness causes you fainting spells, brittle bones, muscles that easily tear, and your pain response is heightened.

It can get hard to breathe with Wind Charge potions, and you suffer from fainting spells from lack of oxygen.
