Buttercup is one of the secondary characters of SPJ and Macaroni’s younger sister. She is a vsco girl, and she sometimes wears shrunchies on her ears and wears oversized t-shirts and carries hydroflasks.
For the evil side of Buttercup, see Hypnocup.
Buttercup’s first appearance was in the first episode, The Beginning Of The Start. She was hypnotized by Hypnoter and became Hypnocup, but then Macaroni and the boys managed to free her. She later appeared in Boast Busters, but only for a short time when she panics about Drent before running off into the street and not being seen for the rest of the episode. She started showing up in the background a lot.
