House of Imite
The House of Imite (Japanese: モノマネハウス Monomane House) is an anime-exclusive location found in between the Safari Zone and Cinnabar Island. It appeared in Ditto's Mysterious Mansion.
Home to Duplica and her Ditto, the House of Imite is where Duplica keeps all of her costumes for which she uses when she dresses up as people. Ash and his friends stumbled across it while seeking shelter from a storm. They found Duplica inside, but she was imitating Ash. Eventually, Duplica introduced herself and explained to them who she was and what she did.
The House of Imite is also where Duplica and her Ditto perform shows for audiences. People come from all around to watch Duplica and her Ditto Transform together into Pokémon and people. However, for a while people stopped coming because her Ditto couldn't transform all the way. Eventually, with the help of Team Rocket it learned how to Transform completely. Satisfied, Duplica reopened the House for audiences once again.
Its English name may be derived from Duplica's Japanese name, Imite, which itself sounds similar to the English word "imitate."
