Only one I've encountered so far is the vendor bought Mushroom pet from the Truffle. No idea how to get the others.

Truffle requires a mushroom biome house in Hardmode. Fairly easy to get.

I got a baby penguin pet from an ice cave chest.

Get with two high level people have them both have turtle shell armors and suicide into the dungeon guardians before beating skeletron. They will 2 shot the guardians leaving you to take the bone key that summons a baby skeletron head pet. Probably one of the rarest and hardest pets to get in the game.

if you want multiple pets then the Pygmy Staff Plantera drops is easy, provided you have a powerful weapon to kill that damnable thing with, if you sue that staff with the Tiki Armor that the wtich doctor will start to sell once you get it, you can have up to 5 Pygmy's AND an adtitional pet of your choice
