Marching March (マーチングマーチ) in a song by HALCALI that was used as an ending for the Weekly Pokémon Broadcasting Station (週刊ポケモン放送局) episodes near the end of its series run. The HALCALI group name is a portmanteau of the two girls in the group, Halca and Yucali.
The ending is an abbreviated and edited version of the official Marching March (マーチングマーチ) music video with a few added Pokémon segments. The video depicts a high school block breaking martial arts tournament with cheerleaders and judges and a crowd looking on in the schools gym.
During the Weekly Pokémon Broadcasting Station ending, HALCALI spend most of the time singing and dancing in front of the cheerleaders near the gym's stage. Pikachu and Leader Kimori both take turns trying to break as many of the blocks as they can.
