Daffy Duck's Movie: Fantastic Island.

Daffy Duck and Speedy Gonzales find a treasure map that leads them to a wishing well, which for a penny will grant any wish (through old cartoon footage). Daffy sets up a resort around the well and various Looney Tunes characters have their dreams come true. Meanwhile, Yosemite Sam and the Tasmanian Devil hunt for the varmints who stole their treasure map!
