Although Fatt was unenthusiastic about the project at first, he went on to become an integral member of the group, having created the popular character Henry the Octopus (in addition to performing as Henry’s voice) and inspired one of The Wiggles’ songs entitled “Wake Up, Jeff!” Fatt was uncomfortable around children during the early years of The Wiggles, and considered those early shows highly traumatic. Fatt’s famous “sleeping” schtick came from Fatt’s real life proclivity for grabbing cat naps in between shows. The Wiggles continue to be a popular children’s TV program, both in their native land of Australia and abroad.
