Gilbert, Shelbert, Norbert, And Missy (Voiced By E.G. Daliy In (When Young) And Voiced By Tom Kenny, Linda Wallem, And Doug Lawrence) Are The Four Children Of Filburt and Dr Hutchinson, who all came from the same egg in the fourth and final season of the show. Gilbert and Shelbert look exactly like Filburt while Missy is a miniature version of Hutchinson. Norbert, on the other hand oddly resembles Heffer since he sat on the egg for Filburt. He also believes that Rocko is his mother/father and constantly follows him around. For most of the series, the four are featured as babies; they appear once as teenagers in the episode "Future Schlock."
