Hint: Bad Mr. Frosty: Stomp on opponent's foot:
Get directly next to an enemy and press C-Right. Bad Mr. Frosty will stomp on the opponent's foot instead of kicking him. This works the same with C-Left, but he will instead of punching, use his nose to poke the opponent. These attacks are not very effective.

Hint: Blob: Fun with clayality:
Do Blob's claytality Ear Chomp (Left, Down(2), Forward, Right) when the narrator says "There goes the ear", something will happen with the character. For example, if you do this against Houngan, he will look at the camera and fall down. If you do this against T-Hoppy, he will jump with pain.

Hint: Easy Insane combo:
Have an opponent's energy bar in the red. Then, do a linker (for example, Earthworm Jim's Dash Punch or Bad Mr. Frosty's Snow Blower). Once you start a linker, keep pressing all of the buttons until you do an insane combo. If this does not work, try again when your opponent is in the red again.

Hint: Endless combo:
Select Kun-Pow and a long stage (Tribal Tower recommended). When the battle starts, charge backward. When you foe is near you, press Forward + C-Right. Then, when the first hit makes contact, press C-Down. When you are hitting, charge and release Away + C-Right and press C-Down again. You can use this as many times as desired. By doing this, you can do at least a 60-hit combo. Note: You cannot do an endless combo in the first round. When your opponent's energy lowers to yellow, you can give more hits. Also, this can be stopped in the higher difficulty settings.
