"Ugh..." Mabel's eyes fluttered open from her sleep. She rubbed her eyes and immediately looked at the empty bed beside her. "Dipper?! Oh no, where is he?" She whipped off the blanket over her legs and got up before falling with a hard thump. She looked at where her legs were supposed to be which was now a scaley pink fish tail, glistening slightly. Her eyes widened and she brought it close to her face.
Around this time, Dipper was also waking up.
The sun shone bright in his eyes, making him recoil. The top half of his body was human and the bottom half was a deer. "Ahhhh! BILL, DID YOU DO THIS?!" Silence. Dipper had a sinking feeling as he wondered what he would do if this was permanent. He raced (as well as he could) to the mystery shack to find Mabel.
