Under the Sea theme - help with event name?

Hi all,

My Girl Scout troop is hosting the annual Girl Scout dance. Our theme is Under The Sea., This event generally attracts Daisies through Brownies (ages 4-11 or so) We're tossing around a few different ideas as far as names goes because we're not sure about just "Under the Sea" or "Under the Sea Ball" but so far nothing has gotten us all to say, "that's it!" We've tossed around:

Jellyfish Jamboree

Jellyfish Ball

Barnacle Ball (no one liked this)

Fish-a-Palooza

but so far it looks like we'll we'll settle for Under The Sea Ball unless we can find a really cool and catchy name. This event is for Girl Scouts and a partner which is usually their father but can be their mother, aunt, uncle, grandpa, etc.
