In the beginning of this special, there was a robot with a mystic key being chased by rats in early Cartoon World. The robot later hid the key in a time capsule dug in the old Cartoon World Zoo.

After a century, the Rat King and his minions stole the key, but SpongeBob, Jimmy, Timmy and B.O.B. took it from them. They went to Kenny, met a creepy, old lady robot, and went to Jenny's habitat. SpongeBob, Jimmy, Timmy, B.O.B., Sheen, Chester, Patrick, Jenny, and Kenny, compete with the Rat King and some rats to find "The Lost Treasure of the Golden Robot" and that is very dangerous.

The old lady robot warned that only the one with pure heart can see through the robot and see the truth and the curse of the treasure is dangerous.
