I dunno what they meant by the runs but i hope sonic doesn't become a monster. He's so fun...

I think it means he had diarrhea.

Oh lol! (⌒▽⌒) thanks for the info! Guess he won't be turning into a monster then.

... Sonic the Poop Monster

I think it's implying that by cooking it he negated its powers and it just made him sick.
