Nicktoons: Attack of the Toybots is about like any other side scrolling beat-em-up. The levels are all laid out exactly the same save for the two DS specific "puzzles" that break up the first part of every level. Sadly, the little puzzles only require you to run your stylus down the screen in order to flip a switch, or to press up on a directional button. Nothing too brain-taxing, and I'm pretty sure they were thrown in at the last minute to appease Nintendo DS fans. Granted, they do serve to break up the monotony a little bit before you get to the second part of each level.
For the first part of the levels in Nicktoons: Attack of the Toybots, you run around a toy factory killing evil toys! It is more fun than it sounds, even though you only have a one button attack. After the Start screen, you pick two characters to navigate the toy factories with. They each have a special attack (most of them just punch, though). I was partial to SpongeBob because he has a long range attack. You can switch between your two characters at any point during the game, and if one of your characters gets knocked out (loses all his/her life) then your other character automatically takes over.
The game never explains it to you, but while you are smashing apart wicked toys, you collect nuts and bolts. At first I thought it gave you more life, but I later found out it is your life for the final boss of each level. Life is collected by yellow stars and fills up each character's yellow meter a little bit. There is also a green meter under the character's life bars that fills up slowly. When the green bar is filled, you can perform an attack utilizing both characters, that smashes every enemy on the screen.
As you are traipsing through the factory, you come across a mini-boss that must be defeated. After that, you get a sort of mech that makes killing the annoying toys a bit easier (and less boring). It also makes it possible to defeat the boss for the factory, and the boss for the end of the level. And, after you've defeated the factory, your character uses the mech to race around a course (each level is different) and collect more nuts and bolts, and unlock pictures of some Nicktoon characters. The race level (you aren't racing anyone) is basically to extend the game and let you get more hit points for the final boss of each level... a giant mech that looks like one of the characters. It can get a little annoying at times, but overall I enjoyed the gameplay.
