I like the Squashling pet, though I lost it when I tried to transfer it to another character then accidently deleted that character. It's still infinitely following around the original character until he dies, though.
Slime or Black cat
Pet Slime for Mobile, and I really want a baby skeletron head.
I like the Baby Skeletron! I lost my Bone Key though...
I'm a big fan of the sapling Especially if I'm running over my skybridge
All of these pets are really grear especially when they are hard to obtainBaby Skeletron Head. Just because it was really hard to obtain
technically pterosaurs aren't dinosaurs so its only one... (closely related but not actually dinosaurs)The dinosaur wins by far, because it actually consists of two dinosaurs, a t-rex thingy and a flying one...
