The Shmoo was an amorphous, full-body-prehensile creature of unknown origin who kinda looked like a bowling pin. He first appeared (I believe) in the comic Gasoline Alley; later, there was an animated series called the New Shmoo about the shmoo and a buncha stoned kids who had trips-er, adventures, especially when the shmoo got a shmoo snack. Or maybe it was L'il Abner?
