What would be a good name for a mare that portrays her silliness and fun

For a fun pony, I'm thinking maybe Jolly, Joy, Giggles or Smiley.

Or if you want to focus on her silly (or even clumsy) side, then perhaps Klutzy or Dizzy.

If you want to try something a little abstract, what about Roffle? As in, how you might pronounce ROFL when just pagbaba the four letters as a word rather than an acronym!

Anyway, I hope these ideas help you in some way! ^^
