In SuperSponge, SpongeBob wants to get a present for his friend Patrick's birthday, and decides to get him an autograph from his favorite superheroes, Mermaid Man and Barnacle Boy. The two will however only help SpongeBob if he runs several errands for them first, like getting them a meal or a facial treatment. The game is a traditional side-scrolling platformer consisting of five worlds of four levels each. In every level, the goal is to collect one particular ingredient for fulfilling the latest errand. Swimming or lying in SpongeBob's way are various hostile sea creatures he can dispatch with a slap from his giant red glove. In addition, he can pick up several items that allow more options, like several different weapons, including a fishing net, a coral blower and a jelly gun - all can be used to collect ammunition in the form of jellyfish or coral which can then be fired. A balloon allows SpongeBob to glide. A beating heart shows SpongeBob's health - should it get too low, he can refill it by picking up fast food items like milkshakes, fries and burgers. He can also collect spatulas - picking up 50 of them awards an extra life. Extra lives can also be found in the form of an extra pair of underpants. Every world ends with a boss battle. One level takes place in Sandy Cheeks' home tree. There, SpongeBob must periodically refresh himself at a water puddle or dry out and lose a life.
The Battle for Bikini Bottom begins with SpongeBob and Patrick playing with their robot toys. The former wishes that the robots would come to life. Meanwhile, in the Chum Bucket, Plankton has planned on creating a robot army and use them to take over the world. Not only that, he will also achieve in getting the Krabby Patty formula. Plankton has created a device called the Duplicatotron 3000, a device used to spawn robots. Unfortunately for him, the robots disobey him because the switch is on disobey. Because of that, Plankton is kicked out of the Chum Bucket. SpongeBob wakes up in the next morning to see his house has been trashed. When he goes outside, he sees Plankton. The latter makes lies to SpongeBob that robots came out of nowhere and wrecking havoc in Bikini Bottom. Fooled by this, SpongeBob plans to stop the robots. By the time he and his friend go to the Chum Bucket, SpongeBob has finally discovered that Plankton is behind the entire plot. He admits that he is planning on using a robot army for his purposes. When SpongeBob tells him that his robots are causing a rampage, Plankton tells him that it is because the switch to his device is on disobey method and tries to get the robots to his command. Unfortunately, a robotic version of himself refuses to allow that and sends a gigantic SpongeBob robot to deal with SpongeBob which he defeats both of them.
