This apple worm wants to eat, so it travels through the levels seeking food. Eat an apple and find the way to reach the black portal in the end.
The tastiest apples are located at the top of the tree, when sun beams make it red and beautiful. It's impossible for some apple worms to reach them, but not for our hero. Lead this brave worm across several levels and make sure it will have all apples around the world. Grow up and proceed to the next level.
