Fangface (1978)

S1E1 A Heap of Trouble

A strange blue creature known as the Heap has been wreaking havoc on inventions across the city just before their big reveals. The gang is invited to stay with Professor Boyd, whose creation has somehow remained safe. The only other professor untouched by the Heap's destruction is Professor Arnos, who was dismissed from the university years ago for conducting experiments without permission. To protect Boyd's home, Fangface and the gang set a trap, but chaos ensues when Fangface accidentally swallows Puggsy. While Biff and Kim work to rescue him, the Heap kidnaps Professor Boyd. The gang follows the creature’s trail, leading them to a shocking discovery: the Heap is actually Arnos, who has developed a ray that can change a person's appearance and is seeking payback against those who mocked him. The gang must figure out how to thwart his plans.
