Prologe
It was a beautiful sunny day at Gravity Falls, the Mystery Shack was open to the tourists. Dipper and Mabel Decided to venture the forest a bit more, "so what do you think we will find in the woods Dipper?" Mabel said, "I don't know Mabel maybe more creatures or animals" Dipper said so the both of them kept walking across rivers and ponds until they reached a long canal. Dipper and Mabel were not planning to swim but they did set up tents to camp there for the night and maybe stay there for a little bit before heading back. So they slept through the night but the next morning they woke up to a weird noise.
They quickly got dressed and ran to the noise with there backpacks,  they suddenly found a portal but it was no ordinary portal it was scratched up with a purple tint and a perfectly shaped crystal with a shape around it. "oh I wonder what's through that portal" Mabel said as she reached through the portal "Wait Stop!" Dipper said just before Mabel's hand touched the smooth surface of the portal. "we Don't Know what's in there" said Dipper, "come on Dipper it looks friendly" Mabel Said, so she proceeded to put her hand through the portal then pulled it out " you see nothing is there" Mabel told Dipper, "uhhhhh fine but only for a little while" Dipper Said angrily.
