Vanna's Fluttershy returns with a throwback to the first season when Flutterbutter admit her prefer brand of evolution! Or is that de-evolution? I guess mammals branched off pretty early from trees? Or did we all start off as a single "race" of single celled life that eventually lead to both trees and cartoon horses?
I should probably know that. I thought I loved science. Maybe I'll google it or something. Anyway, go get Flutters being a tree below.
