When King Viking and his evil robot army attack Animal Town, and kidnap Singing Dog, it is up to Super Rabbit Boy, with some help from Sunny and his video game console, to save the day.

King Viking decides to find another planet where he can carry out his evil plans without interference, and everyone in Animal Town is delighted; then an alien appeals to Super Rabbit Boy for help and he blasts off to once again confront his enemy--but his level one rocket may not be up to the task.

Super Rabbit Boy's present to Moon Girl releases Queen Spooky and her army of ghosts, and Super Rabbit Boy is taken captive--so it is up to the normally evil King Viking (who does not like the competition of the ghost army) and especially his secret weapon, Robo-Rabbit Boy (switched to "Good" mode) to save Animal Town, release Super Rabbit Boy, and contain the ghosts.

Super Rabbit Boy falls down a pipe and discovers himself in a mirror reality where everyone good is now evil, including his mirror self, Super Rabbit Boss, and he must make friends with King Viking (now one of the good guys) and somehow defeat his alter ego in order to save this world--and somehow find a way back to his own reality.
