Ooh! I'm liking these clean Huepow clips!
Also, I've been doing some Moonlight Museum-related stuff recently, and I'm noticing that some of these Klonoa clips are the same ones that were compressed even further for MM, (which I guess shouldn't be surprising since it came right after DtP) but something I found really interesting is that MM used the double-jump Wahoo sound ("Wahoo 2") at what seems to be the original recorded pitch (as in, it matches the pitch in these files), while DtP apparently sped it up a little.
Also, do you know where "Wahoo 1" is used in the game, if at all? I remember finding a similar-but-not-identical-sounding sad Wahoo noise in MM and having no idea where it came from. Now I'm starting to wonder if all of the games have unused sad Wahoo noises or if I'm just bad at remembering things.
