|“||And for being such a big help in all of this, your planet gets to go first! Prepare to bow, Popstar! Welcome your new overlord!”|
|— 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 Pop Star opened by Magolor using the Lor Starcutter's Halcandran technology in order to start off his scheme of galactic conquest.
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 her assistance and the team takes off in pursuit.
Previously, throughout Kirby's adventures throughout on Pop Star 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 Pop Star and Halcandra are sometimes present in these areas, presumably having entered through the rift before Kirby did.
