[TOMT] I watched this show in the early 2000s – Might (very possibly) came out earlier.

I try to describe it to the best of my abilities from memory: It was about these three little monkey like creatures that lived in I believe a forest and story started with a father a daugther pair traveling there without the knowledge about these creatures and when they met the only person to understand them was the girl and she had to keep them a secret. Thats it, oh and if I remember it was like 2,5D animated and looked really nice… Hope someone knows the answer to this question thats been bugging me for a while
