Monsters vs. Aliens
Conrad Vernon as Insectosaurus: Formerly a  grub transformed by nuclear radiation into a 350 ft monster with the power to shoot silk out of his nose. He is unable to speak clearly, and is mesmerized by bright lights (normally used to lead him to other places). He also has a close friendship with the Missing Link, who can understand what Insectosaurus is saying. In his butterfly form, he has wings and is able to fly and becomes the Monsters' mode of transportation.
