Hippie Feet

Hippie Feet: Mumble becomes a hippie, and the other Pen-guans don't liek his decision cuz he can't sing so he gets banished to the Forbidden Shoar where he meets Liarvface and gets captured by Hyoomens and then gets eaten because nobody likes the environment anymore herp derp dper

Hippie Feet 2: Mumble's still a hippie, like his unexplained son, Pillzheer, who sucks at dancing which has become the new craze (Ever since singing started to suck) and they both get banished to teh Forbidden SHoar and Liarvface is ded so a flying penguin takes his place and he's scared of peepull cuz they're gonna eat him and everyone dies.

Also, Mumble flew into a timehole and got warped back to 30 years age.
