SUDDENLY!
He felt a funny feeling in his gut.
"Man...it landed hard there," he said. Then he felt wobbly.
Then, he felt his work gloves getting tighter and tighter and tighter still.
What gives? he wondered, scratching the back of his neck and discovering that he was in need of a haircut.
Suddenly, his work gloves split, revealing, not his regular hands, but something green, and larger, with gnarled fingers that had hairs growing on them. and his fingernails were now much longer, and all ended in sharp points.
That ain't right. Maybe I'm hallucinating, Sid erroneously surmised, but as he went to absentmindedly bite a nail, he discovered that it wasn't just his fingernails that were growing. Some of his teeth were now much longer and sharper too.
SUDDENLY!!!
Sid just so happened to sneeze, and with a snorting pop, his nose changed into that of a pig snout!
"Oh my!" he said. "Those mean uncouth fugitive punks always say I'm a pig, but i guess they never imagined i'd be pig-faced!" He let out a loud snort of laughter.
He almost immediately felt strange... very hungry, too. he didn't even see his belly growing.
