I can't remember the movie or any details :(

So, there's this movie in the back of my mind, but, I can barely remember any details, except the fact it was probably really old (1990's - 2000's) and animated (Very specific, right? 💀) and about like, animals or sum shi-... but I used to watch it a lot, but I can't remember the movie and I'm getting a headache as I try to remember.
If I somehow stumbled apon it and watched it again, I'd remember and be able to finally figure it out.

Well, as someone who can't help, I can't help.
