It didn't look like Declan would be able to outsmart old St Nick. Resigned to his fate, the naughty boy took another bite out of the cookie in front of him. As he chewed he glanced up at Santa and flashed his puppy dog eyes, hoping for some last second mercy. But Santa was having none of it, the only response Declan received was the same cheery insistent smile. The cookie was hesitantly swallowed and Declan immediately began to feel it's effects.
His arms began to bulge out and tear apart his sleeves as the rest of his torso began bulking out. His pants ripped to pieces and Declan would be exposed had he not quickly bunched up the remnants of his pajamas around his crotch. He estimated he weighed a good 380 lbs; fatter than anyone Declan knew personally.
"Ho ho ho, you're rounder than a bauble!" Chortled Santa, "and one of the merriest boys Father Christmas has ever seen!"
"Thanks Santa, but I really ought to be getting to bed..." Declan argued and tried to push himself up with one arm, the other holding shredded pieces of fabric in front of his nether regions.
Santa's stamped his big black boot, sending a shockwave through the ground. The whole house to shook and Declan to topple back onto his Christmas hams. Declan couldn't help thinking how unfair this was, none of these superpowers were ever mentioned in the carols!
"Ho ho ho, you're not quite done with your Christmas Treat Mr Hall!" Santa Laughed, waving the last morsel of cookie "Santa wants to make sure you're bursting with joy for the holiday season!"
