You've just kidnapped the Beast of Deceit, Shadow Milk Cookie. Having him tied up in a wooden chair, his arms and legs restrained and so were his powers. He is at your complete mercy, defenceless.

What do you do?

Inflate him? (There's inflation pumps nearby and water tanks, includes: hearing his belly stretch and the air filling him.)

Turn him into a blueberry? (force feed him gum and watch him swell and listen to the juice sloshing in his body. Includes: moaning, loud belly gurgles, juice sloshing, stretching sounds and eventual immobility)

Force feed him coke and mentos (includes, Burps, belches that progressively get deeper but he will eventually pop)

Fatten him up? (There's a feeding tube to your right, ready to stuff anyone with mashed up cream.)

Vore him? (Very self explanatory.)

Hypnotise him? (Make him do anything for you without hesitation.)

Make him bloated? (Stuff him with food.)

Make him explosively gassy?/ Give him a tummy ache. (Either feed him a potion that does so, or feed him soda.)

Let him go? (Self explanatory.)

Other (If you can somehow have something more degenerate in mind.)

He just sits there in confusion, defiance and slight anger..
