New Super Mario Bros Review
There can be 1-4 players. There are 8 worlds. Each world has a different amount of levels. There are 2-3 castles in each world. The first world is world 1. The last world is world 8. If you beat the levels then you can reach the Green Castle. World 8 is a volcano. When you get to Bowser and when you get close run underneath him when he jumps then jump on the red thingy then he gets bigger and he starts to chase you.
