- This article is about the stage of Mewnic development. For the episode, see Mewberty.
Mewberty is the Mewnic version of puberty.
It starts when you sprout purple hearts when one is around boys, then one molds into a heart-shaped chrysallis and one becomes a purple six-armed fairy and goes after boys. There is no cure for mewberty, for it is just natural like puberty. The stages wear off after a short time, but like many things from puberty, you earn your wings.
