[N64][1998] A character/collectible makes a noise that sounds like "TILOOPI!" when you're near it. Possibly a platformer/collectathon?

As above! I have this noise in my head, it's a high pitched voice. I think maybe it alternates that noises with some general moving noises (hup, hoo, whee).

It feels like a RARE collectathon of some type, or similar? Any help appreciated!
