Red and Ed are a complex duplex that pops out of a coral cocoon in Casey and the Doubleheader. They may have appeared to have large appetites at first (well, in Red's case), but Red proves to be a minor villain - he not only eats Mrs. Kelp's flowers, but destroys Dr. Gallio's lab. They try to eat Casey, but they end up saving her and learn they just have to be nice if they want attention.
