Dedede Mass Attack

In Dedede Mass Attack Dedede is turned into multiple copies after being attacked by a new character, Necrodious, who swallows the staff that can change him back to one, as Dedede is so perfect the universe will implode if there are multiple, leaving Necrodious to take over. Dedede and his new copies go to get back the staff and turn back The beta version of the game shows Dedede turning into copies after a lab accident after which Galacta Goon would appear as a chemical reaction and steal the cure, this would have sparked the first appearance of Galacta Goon's modern design, but this was scrapped and the design was used later in Dedede's Return To Dreamland
