Well, getting into a squirreltaur is easy enough! Just find the nearest one and get yourself in an "unfortunate" situation with them! Y'know, like in an alleyway, behind them in an elevator, just out of sight around a corner... And there you go, you're squirreltaur food!

...The problem is that it can be hard to find one of them, ha. Squirreltaurs aren't horribly common critters. x3
