The Beginning of the End [ Gravity Falls + Phineas & Ferb + Doctor Who ]

The Wormhole

In the morning Wendy woke up with a boy sleeping on her couch.
«Dad!» screamed she.
«What do you want?» answered the dad.
«Isn't it obviously?! Here's a guy sleeping on the couch of my room.» replied she.
«I found him lost in the woods and I brought him for just one night.» said he.
«Ok. I'm going to work.» said she.
«Wait. Take him to the Mystery Shack. Maybe he can get a job there.» said he.
Wendy and the unknown guy went to work. When he arrived they start to talk. He didn't knew his name or how did he came to Gravity Falls, but when he saw Isabella he starts to remember. His name was Jeremy and he is Ferb's sister best friend. But he didn't knew how did he came here. The last thing he saw, was a dark hole and when he touched it, he appeared in the woods. Dipper was hidden behind de door an he heard enough to know that there was a wormhole. Dipper told Ford about it and they needed to close the wormhole, because it will bring the end of the world because of Bill Cipher. He looks like a nice guy, but he brings chaos and disaster. He is a yellow triangular dream demon. He do only exist in the mindscape who wished to gain access to the real world.
