Over at Nick.com (which is Nickelodeon) they have a SpongeBob SquarePants game building. I think it uses the same backend technology as the Star Wars game builder but it is a bit more customized for the SpongeBob SquarePants type of player. The game editor comes with 6 tabs which are World, Level, Hero, Music, Goal, and Builder.

World basically lets you choose a background for your game to take place in. Level lets you choose from a variety of pre-created maps (mainly the ground that you walk on) for you game to take place on. On the Hero tab you choose who you want your character to be. The Music tab is pretty self explanatory and there are twenty or so music tracks to choose from. On the Goal tab you can choose from 3 different goal types which are collect everything, defeat all enemies, or reach the exit. And finally we have the Builder tab where you can customize your level a bit by adding in decorations. There is no custom content that you can upload in this game builder (same as the Star Wars one).

For the most part this game builder pretty much lets you build side scrolling (plus up and down) platformers for SpongeBob SquarePants. The three goals gives you a bit more variety on what type of game you can make. In the end you will probably end up with a fun game because so much of the content is already pre-created. The game builder is built in Flash with your web browser and the games themselves also end up as Flash games. This means all of these SpongeBob SquarePants games will also be playable on Android devices. If you are looking for a game builder where you can build your own games using your own custom content you might try Pulado instead.

On the other hand if you just want to build your own fun little SpongeBob game give this a shot!
