I, too, enjoy video game character themes where the bassline goes all stuttery and a bitcrushed voice goes "bwuh" to inform you that the person before you is in fact some sort of Creature.
There can't possibly be that many examples of this, can there?
It's like a whole trope. I suspect ground zero for the "stuttery bass and bitcrushed 'bwuh's when the Guy is secretly a Creature" thing is probably the theme "Oracle" from 1993's Secret of Mana, though it's possible that's itself referencing some earlier example I'm not aware of:
#oh you can hear the direct line from this to BIG SHOT huh (via @specterthief)
Quite so – for comparison, here's the same character's theme when they're still pretending to be human:
Secret of Mana's "Ceremony"/"Oracle" may not be in the same style as Deltarune's "NOW'S YOUR CHANCE TO BE A"/"BIG SHOT", but the "theme when they're a Guy"/"theme when they're a Creature" transition is 100% playing in the same space.
