She's a two year old baby with pink eyes, purple mane and with a yellow skin, she likes so much cookies and eating lot of them make her use her diaper really fast, speaking in fast she's fast too.

Biscoito has a super interesting story that I made on fimfiction, if you wanna see, I'll will send the link ^-^ (Please ignore the M rate, the rating system of Fimfiction is dumb, they think lot of diaper changes means a no safe story. But dont you worry guys, there's nothing mature here, this story is cute so far if you dont consider her accidents.)
