Cheerilee was Scootaloo’s sister in G3.

can’t see it happening, but I do like the idea, hopefully season 5 will show her parents.

It’s starting to look like a trend, doesn’t it, like they leave their kids in the hands of others. Hell, for all we know, Fluttershy could be her mother. Also, I’ve also come to the conclusion that she’s a ground based pegasus, as in born and lived so far. Even at her age, Fluttershy could at least fly, so I’m guessing pegasi who are born in an aerial based society have an easier and quicker time to learn how to fly. Same with unicorns who are born in a society that heavily uses magic (Twilight Sparkle) versus those who don’t showing potency in magic (Probably Trixie, easily Sweetie Belle).

Cheerille? Because of this one toy description?  
OK that could be semycanon. But I still think it is kinda strange that we know no family members of any of the mane pegasus characters.

Not all characters follow the same color scheme. Technically, Cheerilee should be Scootaloo’s sister.

big sis? I don’t see the relation…
