Blobby is the gray one and Zerk is the brown one, they were both created in a lab as experiments as well as many others of whom I'm still deciding are gonna be in the story - I might make a comic :) Also I'm one of the scientists, the head one actually

Blobby:

Arrogant, cute in appearance, made of slime, angy, bullies Zerk, most popular among visitors, doesn't eat but needs droplets of water for nutrients and moisture

Zerk:

Innocent, loving, scary-looking (almost like a leech?), no hate or malicious intent in a single molecule of his body, When he gets excited (pretty darn often, honestly, because he's just a weird happy ball of energy) he excretes corrosive slime, to eat the fang teeth things on his face open up to reveal a dark hole of which no one in the lab has the guts to research and we feed him meat with a metal claw, he cannot under any circumstances be told that the meat he eats is dead things because he hates violence and is a carnivore so he would stop eating, he can be carefully picked up by a metal claw coated with oils that prevent the corrosion that his slime causes in order to extract the corrosive slime for your corroding needs - he doesn't mind and it doesn't hurt him if done right (if any of my men ever did it seriously wrong and hurt my son they would NOT get off scot free)

It's mostly sons so far but Terry is enby, The Wailer might be enby, I might make girls, there's tons of possibilities
