General Araneus

General Araneus is a character from the 1953 sci-fi film Stand by Your Mantis. It seems he's the good guy in the movie. In the episode Spins a Web, he acted as a villain to Ms. Frizzle and her class as he tried to use Liz as bait for the giant praying mantis. However he plans was thawted when they use the shrink ray to make the mantis the size of a normal one. Upset, he accidentally sets off his own trap (a large fly swatter) and got swatted.
