Tiny Kong's Toilet Trouble

You are Tiny Kong. Since you hit puberty, you've been quite a bit bigger and bustier then your childish older sister. While I act like I don't mind, you've sensed that I resent it at least a little. But you didn't think it would change anything. At least until one day, when using your shrinking power to get something from behind the fridge, you emerged to find you couldn't regrow. You were quickly caught as I came back home, and while you expected me to help, instead I tauntingly announced my plans to shove you right up my filthy little ass.

Luckily all I had time to do was give you a nasty fart to the face before I had to go talk to Diddy, leaving you in a jar on my shelf. You have precious little time, can you find a way to escape the jar and get free, or will you spend the right of your life in your sister's horrific monkey turds?
