What in the world is a "Calm Candy Bar?"

[I love squirtle line]

Ok, so as one of my gold rewards was a "calm candy bar" and on the list of items to sell it is marked as an evolution item but in the games I don't remember a "Calm Candy Bar" so what is it, and what does it evolve if it evolves anything.

I made it, it's my own special brand of sweet and tastelessness. It does evolve something though! Probably some angry fire monkey thing, who knows? Do I? Do you? Do I? Do you? Guess you gotta find out.

angry fire monkey? That sort of sounds like a little thing called primeape.
