If a freak milk accident that sparks life to a half cow, half stegosaurus isn’t weird enough, imagine how strange it’s going to get when Trip Stanley’s class starts drinking the milk! Trip Stanley’s best friend Jules spills a glass of creamery milk onto his uncle’s dinosaur machine and activates the contraption. A creature hatches and grows rapidly into a black and white spotted stegosaurus with and an udder. A stegcowsaurus. When the last bottle of creamery milk that Jules had planned to bring to school for show and tell is knocked over, Trip decides to milk the stegcowsaurus. Everyone in class is given a taste and the reaction causes spots and horns. One classmate even grows a tail. It’s up to Trip to figure out how to de-dinosaur his classmates and keep from getting kicked out of school, all while preventing his mom from discovering the stegcowsaurus in his bedroom. With angry classmates and an upset teacher in his living room, Trip finds a solution in his own advice, when life give you lemons you make lemonade. Realizing the correlation between milk and lemons, Trip reverses the beverages and changes his classmates back into classmates and his dinocow into a cow.
