|— Magolor • Kirby's Return to Dream Land|
Another Dimension is the final level in Kirby's Return to Dream Land. It is the interdimensional space or tunnel between Halcandra and Planet Popstar opened by Magolor using the Lor Starcutter's Halcandran technology in order to start off his scheme of galactic conquest. It is the only level that cannot be accessed from the world map, and can only be accessed after defeating Landia or by going to Dangerous Dinner, entering the boss stage door, and choosing "Final Challenge" from the two options. It is possible the portals within levels with super abilities also lead here, as a large number of Doomer enemies are found here.
At this point, Kirby, Meta Knight, King Dedede and Waddle Dee already realized that they have been misled into fighting against Landia, who was really protecting the Master Crown from Magolor, who previously made a failed attempt to steal it. After Magolor disappears into the newly-opened rift, Landia offers its assistance and the team takes off in pursuit.
Previously, throughout Kirby's adventures on Popstar and Halcandra, there are star-shaped rifts which can be revealed using Super Abilities throughout various stages which lead to dangerous places similar to Another Dimension. They have stark, dark purple environments which perpetually threaten to collapse onto itself, although the usual fauna seen on Popstar and Halcandra are sometimes present in these areas, presumably having entered through the rift before Kirby did.
- Transparent images of the past levels can be seen in the background of Another Dimension. The ones found in the first segment of the level are harder to see, but the ones that appear during the Lor & Magolor battle are more visible.
