In the Game Edit
A purple creature sends you to find the balloon. He tells you that she is trying to kill him. He sends you back to kill the purple creature. She says that he is evil and you have a choice to kill him or her. If you kill the purple creature, the balloon is happy. If you kill the Balloon, the purple creature is happy.
This was the only character I did not design. I was talking with Ethan and asked him to draw a random character. He drew a balloon with a face on a piece of paper. I put it in and it became a character. He was originally going to be voiced by Ethan. He wasn't available by the time I wanted to get the demo out and I ended up voicing him. He got angry and he played the balloon in the full game.
