Representative of the Animal Crossing series as whole for this list. This entry has more personal favorite sound to the voices.

This is specifically referring to the N64 version, which doesn't have full voice acting like most version but instead really good gibberish voice lines that I really wish was the version everything used.

Cutscenes are all voiced normally, but speaking to NPCs will trigger some really good gibberish voice lines https://youtu.be/jjnE4RRcqtk?t=9
