Flare discovers that he's allergic to something around camp, so much so that his sneezing continues to get worse and starts to disrupt all of the camp's activities. Determined to figure out what is ailing him, Flare follows his nose over to Doc Damage's cabin, where he finds Doc experimenting on a scent that he hopes will cause the SUPER PUPS to go crazy whenever they smell it. It's up to Flare to foil Doc's smelly plans not only to save the pups, but his sinuses too.
