Koopa-sama Himitsu Kichi is Baby Bowser's cardboard base in Super Mario: Yoshi Island 3 of the Super Mario Kodansha manga. While the existence of this base implies that the King Bowser's Castle is gone (as also seen in Super Mario: Yoshi Island 2, when Kamek destroys it to make place to Raphael the Raven's planetoid), the castle was still standing in the first chapter set after the game events, implying this was a makeshift base to be near the Mushroom Kingdom. According to a flyer, the base is located in Tokyo, Bunkyō ward, Otowa 2-12-2; which is the same address as Kodansha's Bessatsu Friend editorial office.

The base is first seen in chapter 2, where Kamek and Baby Bowser learn on TV that Baby Peach will board the Akai Pegasus on its maiden voyage, giving them a chance to kidnap her.

In chapter 3, Kamek is seen defecating outside, due to the base lacking a bathroom. Once again, the two discover on TV that Baby Peach will go on a cruise trip.

In chapter 4, Baby Bowser successfully kidnaps Baby Peach and traps her in his base. When the Yossy Helper Team arrive to save her, Baby Bowser activates the Hokaku Barrier to trap them. The machine overloads and explodes, causing the base to go up in flames. Baby Mario, who was not with the team when they fell in the trap, rescues them with his Powerful form. Despite his plan being twarted, Baby Bowser is grateful to Mario for saving him.
