To play this game, use the left and right arrow keys to move the caterpillar around the screen. You need to guide it to the leaves in order to make it grow. As you move through the level, try to avoid obstacles and dangers such as gaps in the ground or other creatures. When you have eaten enough leaves and grown to the right size, you can use the ladder to reach the end of the level and complete the challenge. Keep playing to progress through more levels and see how far you can get!
