Dragon Jelliquids! In-universe, they're hybrids- the result of a marriage between a Gelato ('true' dragons) and a 'normal' Jelliquid. They inherited elemental (namely (element) breath to defend themselves) and size-changing abilities.
First is Dragonfruit Water, he's a guardian of sorts for an ancient temple under the sea. Said temple is for a mostly forgotten deity, that only a few- mostly Water Jelliquids, the oldest species- remember AND worship in modern times. He shifts to a great size to scare boats and underwater tourists alike, but usually his fierce gaze is enough to dissuade people from investigating what he's guarding. When not doing what he feels is his duty, DW generally avoids people and pretends to not care about anyone not in the religious community he's part of. Though simple acts of kindness can quickly change his demeanor and make him let his guard down.
Second is Yellow Dragonfruit Lemonade- or Dragonade as he likes to call himself. He usually has a quadrupedal stance like most Lemonade Jelliquids, but can painless shift to bipedal too (as he has no bones outside his teeth). Dragonade lives in the Celestial Realm, specifically in the Weather Factory where he helps with lightning based products. He's not very good at riddles unlike most Lemonades, as he ends up creating electricity-based answers every time. Despite being a pretty rare hybrid, Dragonade isn't too interested in being 'dragon-like' and loves to tinker with modern fashion, tech and media. His father doesn't approve, but Dragonade doesn't care much. He can electrify his outer membrane if he doesn't want someone to touch him.
Third is Green Dragon Cocktail, Greenie for short, who lives in the Abundant Jungles. Had to crop most of the picture as he doesn't wear much (not that he has anything to hide). His body holds a small terrarium-like ecosystem, with soil and aquatic plants that can survive his cocktail-filled inner membrane. Greenie rarely interacts with people, as he's not only shy but hesitant to potentially encounter someone who would hurt him for his overly conflict-avoidant attitude. But when met with someone nice, he's kind and eager to show his gardens to his new friend(s).
Fourth is Dragon Venom Energy Drink, Venom for short. Normally, Energy Drink Jelliquids need metallic enhancements to let them work with their boundless energy, but Venom is so utterly toxic to the touch, that metal melts on his skin. So for a Energy Drink, he's not as active as his peers, but that just means he's as energetic as an hyperactive human being, instead of uncontainable boundlessness. Venom lives in the Toxic Volcanoes, specifically in one who's particularly deep and where he can swim and not get bored at his surroundings- he lacks legs (birth defect) so he has issues moving fast out of water/lava. Venom is not exactly evil, but is cunning and usually not interacting with benevolent interests. He likes to play with people's feelings, even if he knows he'll never see them again as his home- an active volcano crater- is pretty remote. He just likes the thrill of manipulating others, but also wonders why he doesn't have any friends...
Last is Dragon On Fire Cocktail, and he also lives in the Toxic Volcanoes like Venom does. They know each and are on pretty bad terms. His body is abnormally hot to the touch, but it doesn't hurt to do so- as long as he allows it, that is. Dragire is pretty social, and likes to help local cities with his fire breath (they work on geothermal energy, and sometimes need a bit of heat to not make the volcano they're built on go dormant). Though he was once deeply feared, thought to be responsible for making the Toxic Volcanoes lands barren. He lived with this fearmongering for decades, until popular science found out that, in fact, the TOXIC Volcanoes are the ones responsible for the lack of plant life. Dragire was very affected by this but doesn't always lash out at everyone- but he does have anger and trust issues he does his best to work on.
