The 12th Japanese ending theme features Rocket Gang in their own exclusive ending. The animation features the letter "R" throughout the song, which obviously signifies the first letter in Rocket Gang.
Musashi, Kojiro and Nyarth dance around a stage throughout the song. For the first part of the ending, the song talks about a Rocket Gang meeting where they review what they did wrong during the day.
Realizing that they need to do better the next day, they attempt to increase their motivation by looking forward to the future. The song ends with Wobbuffet poking his head out of the curtains.
