Two scientists want to see what the inside of a beaver is like, though instead of shrinking themselves down to size to fit inside of the beaver, they decide to make the beaver grow to fantastic heights so they can just drive their normal van around inside of him. However, Norbert is dismayed when he discovers that Daggett has been selected as the test subject, so he decides to do what he can in order to get his brother back to normal.
