Chapter two~The sewer.

Dipper

Dipper blinked is eyes open. Ugh... were am I?

As he tried to lift his head up, pain shot through Dipper's body like lightning. "Uh..." He said, gazing around.

Everything was dark, the ground was hard. Dipper blinked twice, trying to remember everything that happened.

Let's see, I walked into the mystery shack, there was a huge black hole, then Mabel-

Suddenly it hit him. Despite the pain, Dipper pushed himself up and shouted,

"Mabel!"

As the pain shot through him, Dipper gazed around, panting. For a minute he lost all hope, then he heard a yawn.

"Dipper?"

Dipper whipped around. Mabel smoothly stretched, lying on a silk blanket. "Good morning, Goofus."

Dipper blinked. "How.. How are you so... Uninjured?"

Mabel casually shrugged. "Just the power of Mabel, I guess."

Dipper gaped, while Mabel gazed around. "What happened?"

Dipper opened his mouth to answer, when suddenly a loud rumbling noise echoed behind Mabel.

"Gross, Mabel!" Dipper shouted.

Mabel blinked, then slowly said, "That... wasn't me."

The twins turned around, carefully watching the shadowy area of whatever they were in.

Dipper felt water underneath of himself. He lifted a hand, gazing at the water dripping down it.

"Dipper, watch out!"

A large rush of dark water was pouring down what Dipper suspected was a sewer.

"Aah!" Dipper shouted.

Mabel turned to him and smirked. "You scream like a kitten, too."
