Doctor Doof in Remnant

To defeat his enemy, Perry the Platypus, the Doctor invents a machine to move objects into an unknown dimension. But because of his clumsiness, Doof himself falls under the action of the inator and ends up in a Remnant. Although the only thing the professor remembered was his name, however, he did not lose his skills as an inventor. How much will the Remnant change from the actions of the pseudo-pharmacist?
