K. Rool's Triumphant Return

The last scene before the credits reveals that the climactic attack on DK Isle was all just an Imagine Spot... but given K. Rool's insanity, it then calls into question how much (if any) of his musical number really happened. In particular, a blink-and-you'll-miss-it shot of Kremling dummies in the tavern, which otherwise only appear in K. Rool's lair, is often seen as evidence that his grand reveal to his Krew was also just in his head.
