Meowth's Party was an interactive technical demo showcased at the 2000 Nintendo Space World convention, demonstrating the Nintendo GameCube's graphic capabilities. In the demo, Meowth is seen entertaining guests at a party with his red guitar. The demo featured Pokémon from the Red, Blue, Silver and Gold versions of the Pokémon video games. The demo was created by the same team who created Pokémon Stadium for the Nintendo 64.
The Meowth in the demo is very likely the Meowth in the anime series, as the anime series itself incorporated footage from the demo in one of its credit sequences (episodes 118-142), where Meowth is seen dancing with associates, Team Rocket members Jessie and James, and their two Pokémon, Arbok and Weezing. In both versions, he likewise shares the same voice actress as the TV series' Meowth, Inuko Inuyama, who voices the character in the Japanese version of the anime series (where the character is known as Nyarth). In the United States, Kids' WB! aired the ending in its original Japanese after one episode, and aired an English dub of the song in the next. Neither ending was ever aired again on the network.
Meowth sings the song at his party in the Pokémon episode titled Pichu Bros. in Party Panic, a special episode only available for viewing on the GameCube game Pokémon Channel. Unlike the rest of the episode, this section uses 3-D computer graphics and Meowth's actions are selected randomly for each viewing.
In Super Smash Bros. Melee, there is a trophy of Meowth holding a red guitar. The character model is the same as the Meowth from Meowth's Party. The description also mentions Meowth's Party and even gives a brief explanation about it.
Meowth's Party (ニャースのパーティ Nyarth's Party) is a mini CD single that was released on October 27, 1999 in Japan. The lyrics were by Shōgo Toda, the songs were composed and arranged by Hirokazu Tanaka.
