Weebo (voiced by Jodi Benson) is Professor Philip Brainard's robot assistant in Jaden's Adventures of Flubber. Unlike some robots, she feels love, and she loves Philip. She was the one who classified the green substance as "flying rubber." When Medfield College sponsor Chester Hoenicker becomes interested in the Flubber, he sent two goons to steal it. Weebo (along with Jaden) tried to defend the Flubber, but was destroyed, and "dies." After getting the Flubber back, Philip creates Weebo's daughter, Weebette. Philip also bequeaths Weebo to Jaden, asking him to take care of her. Wile E. Coyote successfully repairs her, although she has no memory of Philip, Jaden and the others before she was destroyed.
