When the Paw Patrol finds Marshall acting funny, that's bad enough on it's own. But when he starts to disappear for multiple periods of time- usually at night, and then starting to leak into daytime routine- they draw the line. One of their own might be in danger- Mayor Humdinger's card on Marshall's floor is more than enough proof. But their suspicions couldn't be more wrong. NO ONE could have guessed this. A poofy situation...that goes deeper than they imagined. At least no one's going to get hurt. A good caretaker would never let that happen.
