Uncommon Suds

Tom Kenny has voiced ill characters in various cartoons. In fact, he was actually very sick when voicing SpongeBob in the episode "Suds", making the character's illness even more real. The same episode, Kenny was also the guy in the shower during SpongeBob's sponge treatment.

Kenny also voiced the Common Cold in Codename: Kids Next Door; the eternally ill enemy who weaponizes his snot to spread his cold. He only had a major role in "Operation: T.O.M.M.Y.", and the rest of his appearances in the series were merely cameos (M.O.V.I.E., Q.U.I.E.T., A.W.A.R.D.S., etc.). His demotion to extra makes some sense considering the squick factor of his powers. In T.O.M.M.Y., Common Cold silently swore just before getting blasted with chicken soup.

SpongeBob belongs to Stephen Hillenburg and Nickelodeon. Codename: Kids Next Door belongs to Tom Warburton and Cartoon Network.
