Quicker game:
Shoot the fruit on the trees three times until one of the following two things appear:

1. A level where you have to race against time.
2. You have to collect all of the shells.
If done correctly, you will skip some levels. These are the levels where you shoot the apple three times on the tree: Beach, Columns, Rickety Falls, Log Falls, Garlen Beach, Dream Cove, Thicket, and others.

After starting the first level of Cotton island, move left and jump into the water. Continue moving in this direction until your character reaches an island. Shoot the fruit on the tree three times to access a bonus level. Complete this bonus level to jump to level five. Complete this level and start the next level. Move down the hill, jump on the cradle, and avoid the fish. Wait until the cradle rises to reach a floating island. Shoot the fruit on the tree at this location three times to access another bonus level. Complete this bonus level to jump past the Bobbins Brothers to reach Acrrilic and Plok's house.
