Pool Party By Purge Reviews : Splish and Splash!

About Pool Party, from BoardGameGeek:

Summer is here, it's hot, and the pool is calling your name. You decide to join in on the cannonball contest - but watch out! Too many swimmers and this wacky pool can easily spill over, tossing you and everyone else out. Make big splashes in Pool Party by propelling your teammates into the unsteady pool, and be the first to successfully land three divers in to win. -description from the publisher
