Two buttons.

You were riding your bike on a path, trying to get back to your house. You decided to go through the forest to get to your house quicker. Not long after, you realize you might have just made a mistake. A man stops you in the middle of the path. Hes wearing a yellow suit and a black tophat, and he seems very extrovert. After you and the man talk for awhile he starts to like you, and wants to give you something that will change your life. He gives you an option to press 2 of the buttons. Theres a red one, and a green one. The red button gives you the ability to shapeshift anything you imagine. You can become a crazy monster or a cat, but you can only use this ability once. You cant change back into a human when you already shapeshift once. Whenever you shapeshift you can choose your age, gender ect. The green button will give you the chance of giving you a superpower. But theres a 35% that it will be a good superpower, 35% that it will be useless and terrible, 30% you wont get anything.
