Flying Whoopie Cushion
From Muppet Wiki
A Flying Whoopie Cushion appears in the Fraggle Rock episode "Boober's Dream." The Whoopie Cushion is one of the creatures, along with dream Doozers and Gorgs, who inhabits Boober Fraggle's dream world, the domain of Sidebottom. The cushion zooms around the landscape, and periodically utters excited cries of "Whoopie!"
