Ok I just got the game Shrek 2 for gameboy advance for my daughter and we are both stuck and it's driving me mad. We are stuck on Book 1 chapter 4. The part we are stuck on is where Shrek bounces hard on the mushroom and gets up on a ledge but can't get up to the top of the ledge and donkey can't bounce high enough to get where Shrek is. How in the world do you get past this part. Any clue would help, thank you.
