Hello!

self explanatory by title Lizzie, Jimmy, Joey, Shelby, Scott and Xornoth(uncorrupted) are hybrids of whatever they are plus some human elements like Lizzie won't be her cannon hight (after transformation) just imagine Lizzie taller than everyone but not massive but she'll still be a blue Axolotl however the Elf brothers (Scott and Xornoth) will keep everything.

Ships: Jornoth(Joey X Xornoth), Jizzie(Joel X Lizzie), Flower husbands (Jimmy X Scott)
Either husbands (sausage x Fwhip) nature wives(Kathrine x Shrub) that's all I'll let you know of my headcanons later (yes I'll take some from stories I've read in the past cuz I'm uncreative and need to piece things together quickly.)
