Plot
At the Utonium residence, Blossom was given an allowance of $20 by the professor for her good behavior. Pondering what she will splurge on, she goes to the new bakery that opened up last week; she ends up spending $12 worth on a month's worth of donuts and over a sudden developed impulse. Blossom's sweet tooth has started spawning recurring eating habits: eating an entire bag of chips, Buttercup's limited edition bag of Cheese Munchies, sausage and bacon from breakfast, among others.

Four weeks go by and Blossom has become morbidly obese from overeating. As Bubbles gets noted that Princess Morbucks has robbed the Bobbin Brothers Jewelry Store, they rush down there and face off with her. Amused by Blossom's now morbid body, she chases Morbucks after threatening to crush her with her weight, with her dropping the bag of jewels and Bubbles and Buttercup returning them in the process; Blossom unfortunately loses her due from exhaustion.

The Professor catches on to her eating habits, so he brings her to the lab to test her strength and powers, in which fails, leading to the Professor putting her on a diet, to her dismay. Suddenly, the hotline rings and they get the memo that Morbucks is in possession of the museum's priceless diamond, so Blossom goes after her alone. On a skyscraper, she encounters her and successfully defeats her before she could get away. On the following day, Blossom is at a gym losing weight. She apologizes to the professor for recklessly spending. 17 years later, a 24-year-old Blossom, out of shape than she was before, had graduated from Townsville University and returns home to a reunion party.
