I was playing casually, and I managed to trigger a Collector while in a cutscene (namely, the "I'll be your BFF" doll and the Collector right by it)

The tuba sound got really high pitched.

I'm unsure, but maybe check this for other glitchy behaviour? We already know the tuba sounds glitch, does anything else?

This was on a Wii U, with a real disc. I'm using the later PEGI 7 ver, not the original PEGI 12 ver.

HI! cool glitch discovery. I will try it tommorow. only (kinda) similar glitch I know about is this one that randomly happend during a speedrun.
