Danny was having a great summer in Amity Park, at least the five minutes of it before Vlad convinces his entire family to go to a cabin that his company owns in Gravity Falls, Oregon. Danny is suspicious since he feels paranoid that he's being watched; especially in the forest. When he sees gnomes chasing two kids in a golf cart? Now he knows this place is absolutely abnormal.

Music has always been Yuichiro's escape from the world, but when he hears someone playing the piano in the music room one day, a blond transfer student he hadn't previously paid any mind to before, why is he suddenly drawn to this person? Maybe music isn't the only thing Yuu cares about after all. MikaYuu.

It started with Danny trying to keep his secret from the twins. Pfft. That didn't last long, and then Bill had to go along and try to take over the entire multiverse. A lot of bonding, action, and surprises.

It's just a little family outing! No ghosts & no Fenton gadgets for a whole week. What could possibly go wrong?
