中川翔子、ヒャダイン、あばれる君、大谷りん香 (Shoko Nakagawa Hyadain, Abareru-kun and Rinka Otani)
The first opening for Gathering in the Pokémon House? was only a few seconds long. It starts off with a long shot in the sky looking down at Tokyo. The Tokyo Tower is prominent in the shot as it zooms through a bunch of clouds to the actual Pokémon House which has a large Pikachu tail as its roof.
Cut out pictures of Shoko-tan, Hyadain and Abareru-kun pop-up at the bottom of the screen and they disappear as the Gathering in the Pokémon House? (ポケモンの家あつまる？) logo appears for a few moments before it disappears and the camera zooms to the front door which opens to start the episode.
