you got to be lvl 12 or 13 or 14 or 15 i was lvl 15 when i beat him
You have to beat bowser for the second time
You have to beat bowser for the final time then at the end you get world s and then you have to get loads of stars to play each level
The final level in world 8 is bowser's final castle. You have to battle Bowser AND Bowser junior at the same time. Once you beat them, you will have saved Peach and on the bottom screen it will show you how to be Luigi. (Press L+R+A at the file loading menu to play as Luigi.)
Lock the keyhole after defeating Oogie the second time
The same way you beat him the first time - grab him by his tail, swing him around, and throw him into one of the bombs around the arena. This time around, however, he tips the battlefield to try and throw you into the lava, so be careful.
Use different pokemon. They should be at least level 50 the first time and level 70 the second.
You have to level up your pokemon a lot and make them stronger.
First, you beat the giga carrot mission in dimblewood forest. Secondly, you beat the wiggler. (the wiggler should give you the banzai bill for the banzai bill cannon after you beat him) Third, After you launch the banzai bill out of the cannon, bowser's castle will land on top of bowser. Then you play as Mario and luigi and there will be a new place in bowser's body to explore. Then, once you beat the part when you play as Mario and luigi, bowser will turn huge. Beat bowser's castle in a giant battle. Then, you a new place will appear where you will then be in bumpsy plains. Make it through bumpsy plains. Then, all you have to do is get through bowser path and there you have it.That's how you get to Bowser's Castle (lucky i didnt explain it all the way through, or you would be readin this for a long time)Not that on the way back, there's A LOT of those weird doggie bom-o thingies with the Fawful head.Fawful: GET A NEW LOOK!
It is on level 4-10 when you play it a second time once you beat the game
I recommend you keep a Mega Mushroom and when it's boss time, take it, stomp Bowser Jr, and jump on Bowser.
when you go to the bottom floor of the bathroom!
It is not an easy task to beat the robot on level three of cat Mario. In order to do so you must face and beat a list of difficult tasks. However, once you get to the robot, you will have to hit a block, throwing weapons at the robot, who will jump on a trampoline. At that time, you will have to run into his arms, and he will throw you to Bowser and you will win.
