While escaping a rainstorm, Ash and his friends enter what at first seems to be an empty castle. Soon after entering, they hear screaming and rush to the source, which turns out to be people receiving medical care from Pokémon. As Dr. Anna introduces herself, her assistant nurse, Keiko, reminds her that it is time for the Zubat scan. The group follows Dr. Anna into the procedure room, where a Zubat wearing a green bow hovers over a man and uses its supersonic sound waves as an ultrasound. Dr. Anna explains that her clinic uses Pokémon to diagnose and treat medical problems in humans. Machoke uses its strength to treat back problems, Spinarak uses its web to make bandages, and Mareep’s electricity stimulates muscles. She explains that the Pokémon and her work together, and the Zubat with the green ribbon is revealed to be nicknamed Mimi. Misty asks why she works here, to which Dr. Anna explains that a patient of hers used to live here and now lets her run her clinic in the mansion.
