It then accidentally knocks over the cloning formula, which drips through a crack in the floor and all over an "Ocean Pups" kit.
When Victor and Conrad find out about Will ordering the kit, they decide to spy on the house and take the possible clone back to the lab for experimentation.
While working with the kit, Will accidentally clones himself after stirring the water with his comb that has his hair on it that contains his DNA.
At lunch, he enjoys eating pizza for the first time and dances with everyone else; he ends up going to the principal's office for causing a commotion and makes amends with Will's old rival, Scotty DeSota.
While the real Will spies on them, he finds that Twoie has only a few hours before he turns into Ocean Pup eggs, as clones have a four-week lifespan.
Twoie comes and rescues him, having learned his location from the telepathic connection they share, and helps him keep the scientists down.
The cops get suspicious, but Will makes up a story that Twoie is his identical cousin Gil Pupman from Belgium, and everyone (except for the scientists) back him up, despite being shocked.
The film ends with Gil asking to have pizza for dinner, and the family wholeheartedly agrees.
