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 o Smiley.

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

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

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