School's out for summer, and it's vacation time for the Tiny Toons gang from Acme Looniversity! Babs and Buster Bunny's vacation starts with a good old fun-in-the-sun squirt-gun fight! Once the flood gates are opened (and all of Acme Acres is under water!), they are swept away on a summer adventure of a lifetime. Plucky joins Hampton J. Pig and family for a road trip to none other than Happy World Land - the greatest theme park this side of the globe! From the endless annoyances of Hampton's family to escaped convict hitchhikers, Plucky is in for one long and very hot summer! Elmyra is in wild animal bliss as she visits a drive-through nature park. Will the animals survive her unique brand of affection?
