Hint: Giant polar bear:
When Shaggy battles the giant polar bear, it will charge at you, spin at you, and throw small, medium, large, and extra large snowballs (which knock you off the ice).

Hint: Defeating the first Boss:
When Scooby is fighting the first Boss, he will try to hit you with his sword. When he shoots the fire, stay in the corner, but in the same lane as him so you do not get energy taken away if they hit.

Hint: Egypt level 3: Extra pies:
Two mummies will appear at the start of the level. Instead of throwing pies at them as you are supposed to, just avoid them and collect as many pies as you can. The maximum number of pies you can have is 99. This will give you more than enough pies to kill all the other mummies that appear.
