When his feet are blinking, tackle him from the side of his foot. He will turn over. The mouse will then pop out of the bear's head. Tackle him from the side of his head. Repeat this until he is defeated. Note :If you are an advanced player, try tackling the mouse two times each turn.

Hint: Defeating Batcat:
When you first start, a bat will emerge from the cat's head. Then, the floors will collapse. After that, the cat will dip down in the water and produce a wave. Jump on top of it and tackle the bat (B + Right). Do this until the bat explodes. When this happens, the cat will shoot explosive spike balls; avoid these. The cat will still shoot waves. Then, as before, jump on it. Slam down on the bald spot on the cat's head. Do this until he is defeated.

Hint: Defeating Cuckoo Condor:
When you get to Cuckoo Condor, stop by the Item Shop and pick up the Big Fist. When the Big Fist is used, Cuckoo Condor should have just a little life remaining. When he shoots the shock wave or the saw, jump over them and stand under the claw for a split-second, then run away. The claw will reach down, trying to grab you. When it reaches down, hit it. It will swing up and hit him in the head. When the bird breaks out of the clock, it will shoot eggs. If you catch one, hold it. When they break, small ducks will appear. Do not touch the ducks -- they will hurt you. Keep the egg and when the bird returns (he has to face you), jump up and hit him on the top of his head with the egg.

Hint: Defeating Cractus:
When you collect all the stones, go through the door that takes you there. Instead of fighting Cractus, go to the Item Shop. If you have enough medals, get the Big Fist. After you use the Big Fist, climb up on the ladder that is hanging on the wall. When Cractus appears, if he is not drooling, jump up off the ladder and down-pound (Jump then Down) on his head. Continue until he is defeated.

Get ten or more Froggy Coins and choose the Black Dragon. It should leave him with 2 HP. When he is chainsawing you with his leaves, go on the ladders and do a Butt Slam on him. Repeat this two times. Note: The Froggy Coins are obtained in the bonus games and not the levels.

Hint: Defeating Golden Diva:
When the battle starts, her face will duplicate four times. They will rotate around the fan she is holding to cover her true face. Then, one will become brighter and break from the rotation. Jump on it. It will fall to the floor, changing the face and turning silver. Do an upper charge throw by holding Up + B until Wario flashes. When the fan gets close to you, release B, then Up. Do this several times until the fan breaks. She will then drop small green ball-like creatures. Jump on their heads and do a regular throw by simply jumping, holding Up and pressing B. She will then drop a large blue ball with a bear on it. When you tackle it, the ball will go diagonally up from the direction you tackle it. When the timing is correct, tackle it and make it hit her face. She will now start laying black spotted eggs. Catch one, then hurry and do a regular throw to her face before it explodes. She will now throw a spiky hammer. Let it drop. When the spikes disappear, grab the hammer. Do not throw it at her. Instead, throw it lightly in the air, staying on the ground. Let it hit you on the head. You will become Springy Wario. Press A at the correct moment to bounce upward and hit her face. Repeat this until her face becomes red. Hit her about three more times and her face will stretch upward and she will start butt-slamming the ground. When she does, jump out of the way and tackle her face from the side. Repeat about three more times and she will be defeated.
