Unlockable: Drumstick
Throw a frog at the green sillouette shaped frog picture in the world map Then stomp the frog that comes out.

To clarify, all you have to do is get a frog you jump on top of the frog shaped area that is surrounded by water. Fly around the main area that features Taj's tent. You will eventually see the "Frog Island."

To get the frog to jump, you will notice that when you approach one there is a hand icon. (When you see these, it always means there is a stylus involved in its interactivity.) Take the stylus and stroke the frog in any direction slowly. You will notice as you are stroking it with the stylus it stretches in the direction you are stroking it.

When you let go of it it snaps into the air depending on how much you stretch it, andin what direction you stretch it. If you get it to snap from any location, into the frog island, you will recieve Drumstick as a universally playable character. There are only four other characters left that are hidden.

Hint - Super Boost
Before landing on a zipper or using a blue balloon, let go of the acceleration button to get a much faster and longer lasting boost then normal, this boost will look and sound differently then a normal one as well.

Hint - Hidden Balloons
Go to the icy section of the world map and locate a ramp that zig-zags upwards. A balloon is frozen in an ice block at the top. Drag the frozen balloon down the ramp and the warm river water will melt the ice.

On the left side of the ocean section of the world map you will encounter a monolithic henge of stones. Click on the stone henge and proceed to draw a balloon shape that touches all the stones. The image you render should resemble what the shape of the balloon looks like.

Hint: Cracked wall
When you go into the log on thhe mainland there will be a cracked wall with a pic of wizpig. Draw around his head, outside including ears, and the wall will crack. A bonus coin card will be on the other side.

Coin Making Craze
Way 1
Take the stylus and shake trees that are in the area around Taj's Tent. (Take your stylus and tap the trunk of the tree. You should here a creaking sound. One you here the creaking sound, move the stylus back and forth quickly. If you do it right you should hear a sound and the coin wil appear on the ground near the tree, and on the map. This cheat can be used infinite times! Once you shake all the trees in the area go away and come back and you will be able to do it again.

Way 2
Go to the coast near the water fall that is under the log tunnel. After you get there, you should see little dots in the sand. (This area is to the left of the water level's entrance) When you are approaching it, you should also see a hand icon like you do at the cracked wall where you find the discover card. Tap the hand and you will have an overhead view of the sand. You will notice two round shapes formed by the dots. One in the inner part, and one on the outer part. Connect the inner dots as best as you can be making a small circle from connecting them. After you are done, push the back button (top right). If you did it right, you should hear the same sound as you do when shaking the trees. After you hear the sound, there will appear about ten coins. This cheat can be used multiple times, but not infinitely.
