I always request raccoons, and I think it will fit well with the theme so far.
Maybe also a female character of some sort. See some suggestions that follow;
1. An adventurer or something, attacks with a whip?
2. A witch with magic spells?
3. A princess with a really cool rapier?
Pirate! You have a ninja.
The above is more what I really want to see and use. The below is more things I could use.
Otherwise
Ferret, squirrel, chipmunk
pig/hog/goat/sheep
Horse, deer, zebra, moose.
Bison/buffalo/cow
Tiger
Even more dogs/wolves.
