Fred has entered the Science Expo in Houston, Texas with a monster trapping project involving magnets, a trampoline, and a sticky net. A girl accidentally gets caught in the trap but is quickly freed by Fred. She catches Fred's eye (much to Daphne's dismay) and identifies herself as Melanie Staples, daughter of NASA Scientist Ned Staples. The gang checks out her father's demonstration where he unveils a large robotic dog, "Mecha Mutt", equipped to travel over Mars terrain.
