From my webcomic Itsy Bitsy Adventures.

Bitsy Poof is a short and stubby pony who's always looking for adventure, and often drags her friends along for the ride.
She is playful, imaginative, Most of her weight comes from her hair and she probably has some sort of ADHD or something.
She lived in the city of Trotsbury until an alien invasion began.
