Entry location: At the end of every castle
Here's how to beat all the bosses except in world 4 & 7.
World 1. Bowser-Go on the platform. Then jump over him and hit the switch.
World 2. Zombie Catapillar- Keep on jumping on his head.
World 3. Big Cheep Cheep- When he jumps out of the water, jump on him.
World 5. Petey Perana-When he smashes down to the ground, jump on him.
World 6. Monty Mole's Tank-After he's done blasting bullet-bills he'll come out of his tank. Jump on him.
World 8. Bowser's Skeloton-Jump over him and hit the switch.
World 8 - The big castle. Bowser J.R and Skeloton Bowser- This boss battle was hard so I cheated. Get a Mega Mushroom and eat it at the boss battle, then jump on the 2. Next hit the switch.

Entry location: any boss (or mini boss) level
to beat Bowser Jr. easily, just make sure you're fire mario. repeatedly throw fireballs at Bowser Jr. and jump over him when he charges. this should take a total of about 10 seconds.
To beat a regular boss easily, put a gigantic mushroom in your "stash" on the bottom screen. Then, when you have started the battle with the boss, tap the mushroom and become giant Mario. jump on the boss and he will die immediatly.

This helps for when you are fighting the bosses of worlds 2 and 5. Whenever you try to hit them, don't jump, ground pound. Instead of needing 3 hits, they'll only need one more after you successfully ground pound. (this is when you use the mini mushroom)

Entry location: World 1- Level 5
Get to the bouncy mushroom where the 4 bricks are. Go under one and keep on bouncing up until it done. A mushroom should pop out. If it doesn't try it on another brick.

Entry location: World 1 first castle
Enter an item hut and get a blue shell. Next, enter the first castle in World 1. When you enter the cannon pipe, go into the room with moving blocks and go into the gap on the right side of the wall. You will warp to a room. Use the shell and break the bricks to go into the red warp pipe. Touch the flag and the walk way to the cannon will open. Go to the cannon and blast to World 5.

Entry location: World 1-4, 1-5
It is much easier to beat these levels: 1-4 and 1-5, with Luigi, or super mini Mario. To get Luigi, hold L and R, then select him. To get super mini Mario, get a mini blue mushroom. There are very skinny pipes in 1-4 that only super mini Mario can fit through. For 1-5 you need someone who can jump far/high for the spaces between the giant bouncy Mushrooms.
Hint: You must have very good timing to beat 1-5. If you just can't beat 1-5, go to 1-A and beat that level. Either way you will get to the boss of World 1.

Turns normal Mario into super Mario. These mushrooms move towards you and jump during the "ba ba" of the chorus.
Green 1-up mushroom
Gives yo one extra life. These mushrooms move towards you and jump during the "ba ba" of the chorus.
Turns normal or super Mario into Fire Mario. You can only get a fire flower from a ? block when you are super or shell Mario. Fire flowers usually stay where you left them.
Shrinks Mario to micro-size. Mario can walk on water, fit into tiny pipes, and preform floating jumps. Mini mushrooms move and jump in the same way as the others.
Mario gets a blue shell on his back, and can duck into his shell and run, becoming nearly invincible. You can only get these from flying ? blocks, mushroom houses, and on some courses. Shells usually stay where you left them.
Mario becomes temporarily invincible. Most blocks containing a Starman are hidden, but not all of them. I haven't found out how Starmen move, but I'm pretty sure they are unaffected by the song, and that they move away from you.
