Springfield Pool Mobile

And the Simpson pool, as well as "Rear Window" Bart, maybe the barn before the pool, the Amish as a character (better than those shiftless Mennonites). Sounds like a decent "Summer" quest. Maybe add other "outdoor" activities like the trampoline or add in the Simpsons going to the beach; add in the "cool" kids and a seashell skin for the Simpson car.

Sorry, got carried away.
