The Zap Trap is design to trick the victim into noticing a hot robotic female animal (such as Road Runner or Coyote). Once the victim notices the robotic female animal, The Hunter will press a button that will turn the robot into a cage.
After the Jr. Jet incident, Calamity goes off and buys a Zap Trap, In hopes that it will trap Little Beeper once and for all. As Beeper runs past the trap, the robotic roadrunner drops a hanky and Little Beeper goes to pick it up. Thinking this might work, Calamity waits for Beeper to get closer to the trap. Unfortunately, Beeper uses the same remote and turns the robot roadrunner into a robot coyote, who catches the attention of Calamity and both begin to kiss. Suddenly, Beeper uses the remote and Calamity is trapped inside the cage. While inside the cage, Calamity notices a smell and sees Fifi with him. (How she got into the cage is never answered.) At this point, it seems hopeless for Calamity to escape the cage. Luckily, Fifi's stench melts the cage into a green ooze, giving Calamity the opportunity to escape.
