No Export for You: One Kirby spin-off game called "Kaabii no kirakira kizzu" (Kirby's Super Star Stacker) for the SNES (Super Famicon in Japan) never got released outside of Japan. The 20th anniversary Dream Collection seems unlikely to make it to Europe and has definitely been ruled out for an Australian release.
Urban Legend of Zelda / Word of Dante: No, despite what Mushroom Kingdom Fusion may have told you, 02 did not make any sort of "pact" with Drawcia. Nor is Dark Nebula 02 under another name. The latter theory has been officially Jossed by the Dream Collection Encyclopedia (though it does state that Dark Nebula is part of the same species as Dark Matter). Meta Knight also wasn't possessed by anyone during the events of Kirby Super Star.
