Fossils: Everything in the alternate dimension is supposed to be worse than the normal dimension. Since the alternate dimension is supposed to be more evil than the normal one, the good characters such as Perry the Platypus and Phineas and Ferb are more evil; and Dr. Doofenshmirtz is a lot more evil than his counterpart in the normal dimension. The section titled "Production Information" on the movie's page also mentions this.
