Beat RC without Rocket Skates
In the neighborhood level, when the race with RC begins follow the track as normal. As soon as you see RC behind you, do your spin attack (down c) and RC will briefly stop. This will give you enough time to take the lead again. Keep doing this and you will win the race.
Beat The Attic Robot
Inside Andy's house (In the attic) there is a robot you need to beat to get a pizza planet token. You're laser won't hurt him so you need to make him cahse you until he needs to recharge. Then use your spinn attack on him. He will start chasing you again. Repeat the prosses until the robot is dead.
Beat The Slime Boss
On the Slime boss level, everytime you shoot the slime monster it shrinks down into his trash can. Shoot the slime monster untill it's whole body is in the trash can, it will loose energy by doing this but each time it goes down into the trash can, the slime monster gets bigger so it takes more time to shrink it down. Just get it down in the trash can about four times, then it will die.
