Jake is taken to a cell very near Dean's.
As the one in charge comes in Jake tries to explain that he and Dean didn't want to be on the boat. They had changed their minds.
As he begins to spew out this pleading he begins to get an ache in his stomach. Bending over and holding onto himself he finds himself feeling heavier and drops to his knees.
His mouth grows rounder and rounder as does his body. He expands in all directions His clothes becoming metallic and soon he is coming close to filling the room. His mouth about 4 feet in diameter is now at the front of the cell and his ass busts through the back end looking like he has a tail high in the air.
In the other cell Dean's interrogator entered and soon he is growing tall. As soon as Jake's ass busts through the wall he is growing up and out the top of the cell. His ass links up with Jake's ass and his mouth goes up toward the top of the boat.
As the transformation completes the two become a boiler to power the boat. The hulking men start to toss shovel after shovel of coal into Jake's mouth and the fumes are expelled from Dean's mouth. The two are conscious of their use and Jake sees every ounce of coal going into his mouth and he feels his body heavy from the steel form and the loads of coal entering him. He feels the fumes heading out his ass and linked up with Dean's ass. Dean feels himself linked with Jake and he is often blinded by the smoke coming out his mouth.
You see my boy, the one in charge says, you seemed to spew out all sorts of garbage by opening that mouth of yours. Well now things are going the other way. You wont be able to talk and all this coal will be going into you. And your friend Dean seems to be your butt monkey so you two are linked together till we are finished with you.
Jake watches as more and more coal is shoved in his mouth and watches as the others in their pens are turned into all sorts of animals.
