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 या Smiley.

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

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

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