SpongeBob SquarePants: Battle for Bikini Bottom

SpongeBob SquarePants: Battle for Bikini Bottom is a video game for the Game Boy Advance, Nintendo GameCube, PC, PlayStation 2, Xbox 360, and Xbox consoles that is based on the television show SpongeBob SquarePants. The player attempts to defend Bikini Bottom from an invasion of robots created by Plankton (with a machine called the Duplicatotron 3000), who has lost control of them. The playable characters are SpongeBob, Patrick, and Sandy. However, for the PC version, the game is a series of minigames.

Beginning
Plankton creates an army of robots but forgets to switch the Duplicatron's "Obey Plankton" switch.

To defeat these robots, SpongeBob, Patrick, and Sandy have to collect golden spatulas, which allow them to advance to different parts of town and eventually enter the Chum Bucket. SpongeBob is armed with the Bubble Wand for mêlée attacks, and the Cruise Bubble and the Bubble Bowl for ranged attacks. He also has the Bubble Bash to attack yo momma and tikis in the air. Sandy has the Lasso, for ranged attacks, which can also be used to glide and swing from hooks, karate chop, and karate kick. Patrick has the ability to pick up and throw things, including tikis (some of which explode), Freeze Fruit and Throw Fruit, and he can also do a body slam.

Some areas are: Bikini Bottom (acts as a central hub), Goo Lagoon, Downtown Bikini Bottom, Sand Mountain, Rock Bottom, Kelp Forest, Jellyfish Fields, and the Chum Bucket.

This game is also the introduction to a new character, Prawn. In addition to the several regular robots that litter the levels, SpongeBob and friends will defeat four boss robots along the way: Robo-Sandy, Robo-Patrick, Robo-SpongeBob, and Robo-Plankton. Along the way, they will tangle with three semi-bosses: King Jellyfish, Prawn, and the Flying Dutchman.

In the concept art, you can see that a Robo-Squidward was originally planned to be in the game, possibly as a secret boss. This was scrapped before the game's release. But in the Gameboy Advance  version there is a Robo Squidward!

Also in the GBA version, King Jellyfish, Prawn, the Flying Dutchman, and Robo-Plankton are not present. Robo-Squidward is the penultimate boss, and Robo-SpongeBob is the last boss.
