Bill was an ordinary teenager who worked at the Mystery Shack. But he was more interested in the mysteries of Gravity Falls. Where did the anomalies come from in this place? He wanted to be Stanford's assistant, but Stanford treated him like an ordinary, useless child, so Bill decided that he would solve these mysteries alone

Although it was hard to call Bill an ordinary teenager. He was tall, with strange hair that was slightly yellow, although it was blond. A strange birthmark on one side of his face that looked like a triangle.. In general, because of his appearance, almost no one communicated with Bill, only Wendy and a couple of her friends.

Today, there was neither Stan nor Ford in the Mystery Shack, so Bill slowly fell asleep at the checkout and finally, hitting his head on the table, he fell asleep. He opened his eyes again, but everything around him seemed strange and he realized that it was a dream. Before he realized it, he saw a figure in front of him...
