Plot

After the events of the previous game, Qbby, Qucy, and Qudy travel through space in the Box Ship to restore various planets which have been destroyed by the Black Smoke. On each of the three planets, Qbby encounters a Qbaby in need of help. Qbby helps the Qbaby and escorts the Qbaby to the World Map, where it stays there.

Once reaching the final World in a planet, Qbaby creates a being similar to Planetron out of the ground underneath the final World Door, which gives Qbby various special abilities such as the Rocket Box and Bombox. Upon completing the final World of a planet, the Planetron-like being goes back inside the Qbaby. The Qbaby then sacrifices themselves on the Planet's machine, which removes the black smoke on the planet.

After beating the first three planets, a giant wormhole makes a fourth planet appear, which is covered in more black smoke than the previous ones. The Box Ship fires three machines at its surface, and the black smoke planet fires black smoke projectiles at the machines. Only one machine makes it to the surface, but its top part gets destroyed by one projectile. The black smoke planet loses a significant amount of black smoke, and the Box Ship heads there.

The black-smoke Planet does not contain a Qbaby that needs to be escorted. Rather, once reaching the planet's final main World, an unknown Qbaby-sized box covered in black smoke wakes up temporarily and makes another Planetron-like character out of the ground, then mysteriously disappears in a cloud of black smoke.

Qbby steps out the final World Door, and the fourth Planetron-like being transforms into the top part of the planet's machine which was destroyed. Qbby enters the machine's hole and closes his eyes, but a geyser of black smoke interrupts and attacks Qbby, preventing him from using the machine. Suddenly various boxes hit the geyser and plug it. These boxes apparently came from Qucy and Qudy. The machine's hole became a much bigger hole in the process, so Qbby, Qucy, and Qudy jump into the hole and close their eyes as the machine starts working again. The black smoke piles up around them, and as the camera zooms out, the power from them causes the black-smoke planet to explode, saving the galaxy at last.

In the post-credit scene, three of the Qbabies have somehow woken up and arrived on the Box Planet. They run around for a bit before stopping in front of three boxes which are greyed-out. If one waits long enough on the "The End" screen, Qbby seemingly opens his eyes for a brief moment before closing them.

Trivia

• It is speculated that, chronologically, this is the final game in the BOXBOY! series, with BOXBOY! + BOXGIRL! being a prequel to the BOXBOY! Trilogy.
• The game's logo contains a Qbaby with a purple colored corner, but this Qbaby does not appear in the game at all. It is possible that this Qbaby is the small box covered in black smoke that appears when entering the final main world.
