A quote from TvTropes:
Turns Red
Also known as "pissy boss mode", it is kind of a second wind that enemies get when they've been damaged too much, or when they're the last enemies on the screen.
And man, was Banaan pissed when it got hit. It threw an epic hissy fit.

Remember when raocow collected a heart, and two brick fell down? If you go back to it, it also get's higher, building a pyramid. Apparently, it builds when you do/collect stuff. I wonder if a door will appear when the pyramid is finished.
