Spongebob Squarepants: Creature from the Krusty Krab has a little bit of everything when it comes to the game's controls. There are levels where you will have to race cars, fly rockets, guide a giant Plankton and many, many more crazy things. Most of these controls took a little getting used to and fine tuning, but by the game's halfway point, you get to sample pretty much most of the different controls you will have to know in order to beat the game.
When driving a car, you turn the Wii-mote sideways and treat it like a steering wheel. "A" is the accelerator and "2" is the brake. When guiding a rocket or plane, you turn the Wii-mote vertically and treat it like a joystick. In levels that have a more platformer feel to them (Patrick's comic book dream, or the giant Plankton level for example), the controls go into a much more familiar style that pretty much anyone who has played another platformer on this system (or others for that matter) shouldn't have much trouble picking up.
The crazy controls don't end with the Story Mode though. In fact, the most interesting controls come in the Sponge Band mode where you will have do do an even wider variety of actions in order to play music. For instance, the drums can be played by swinging the Wii-mote and Nunchuck in the air as if you were playing ... well, the drums. Pressing different buttons tells Patrick to hit different drums on the set. The harmonica is played by guiding the instrument left and right in front of Spongebob's mouth while you play the trombone by pulling the Wii-mote to and away from the TV. Plankton's synthesizer seems to do something different with each motion of the controllers. There are other instruments of course (Harp, Whistle, Maracas) and each of those has their own semi-intuitive control that just adds value to this off-the-wall mode.
Creature from the Krusty Krab was a fun, if not all too short, game that I really enjoyed and would recommend to most gamers. This is a title that, even though it is cross-system and thus could have easily been "just a port", really showcases some of the ways the Wii-mote's functions can be used. If you are a Spongebob fan and you have a Wii, then this is definitely a game to pick up. Heck, even if you aren't all that into the little guy, the use of the Wii's controller might be enough to pull you in anyway.
