615 pounds? Tiffany Dino must lose weight! Tiffany Dino hopes the groceries she crammed into her bus will last through the week: 30 pizzas, 25 quarts of milk, 14 jars of peanut butter, 21 loaves of bread, 43 boxes of cookies, 18 bananas, 15 pounds of nuts, and 10 bunches of grapes.
On her way home she passes all her dinosaur friends - and every one of them is exercising! Tiffany decides it's time for her to jump on the bandwagon: she jogs; she dances; she does cartwheels. But she just can't seem to lose those pesky 15 pounds to get back to her normal weight-600 pounds.
Then Muffy moves in. Muffy is gorgeous, big, and beautiful, and the best part of all - she weighs over one thousand pounds! Suddenly, Tiffany forgets about losing weight and makes a most important discovery.
