Me and few other players suggested many of them, here are mine:
https://forum.partyanimals.com/d/1084-few-new-animal-suggestions
And since GrannyMax (an admin) said, they plan/working in the background on turtle, panda and red panda already. Plus i could suggest better for search 1st on forum are there any other forum topics, where other players maybe suggested same and/or other animals already, or not. If yes, no need new animal suggestion forum topic. I said this, because there are so much (bit too much) animal suggestion forum topic already.
