On a planet made almost entirely out of gold located in the Jewel system, live the Bullions. They have lived there peacefully for many years, until their home was attacked by the Drizzletroopers. Two of them, Zig and Zag, manage to escape to Earth . The Leader of the Drizzletroopers learns of this and has someone go after the two. As morning on the big green planet comes by, Buster Bunny and the gang attend Acme Looniversity. However, a strange robot, disguised as Bugs Bunny, appears in their class rather than their teacher. When his disguise is blown, the group chase after the fleeing robot. After stopping the robot from getting away, he makes an attempt to kill everyone, but ultimately fails, leaving a hole in the ground. There, zig and zag appear out of the hole, startling the group. The strange creatures explain their situation and the group agrees to help them. However, Shirley appears telling the group a great danger will fall upon the earth if they help them. Despite her warning, the group decides to help the creatures out. They all enter the hole into the ground, leading them into yet another new adventure...
