A quarrel over the television leads Zapper to try using his younger brother Zipper — a grub — as a TV antenna. Before anything can be sorted out, an infamous thieving magpie named Maggie swoops in, snatches Zipper, and leaves an egg behind. Zapper is not interested in the trade. He sets off to retrieve his brother and bring Maggie to justice, finally succeeding after defeating her and, in the end, setting Zipper up as the antenna anyway — just in time to watch TV alone.
