MONK, equipped with mask, fins and dive tanks is scuba diving. He swims happily, albeit a bit awkwardly, underwater. While swimming past an underwater grotto, he finds himself face-to-face with a Great White Shark: MOUCH. MONK panics and tries to get away but MOUCH follows him. He realizes that the shark isn't out for blood, but just wants to play with him.... A series of 'go fetch' scenarios follow where MONK tosses a shell to MOUCH, who retrieves it. MOUCH is tireless and MONK gets fed up with the game quickly. He tries everything to shake MOUCH off, but he's like an excited puppy. MONK gets fatched and ends up attracting hoards from the CRAB-BAND, to the great amusement of MOUCH.
MONK wakes up and is about to make himself a big breakfast when he checks his calendar and realizes it's KIMMY's birthday. He totally forgot. Panicking, he rushes to make a birthday cake but everything gets messed up: the cake recipe blows away and is accidently swallowed by a parrot. MONK decides to improvise, which inevitably leads to the first of many bad choices that end in disaster. Finally, MONK ends up taking off into orbit on his stove and crashes into the middle of KIMMY's yard, spoiling her birthday party...
