Personal headcanon blah: Planet Robobot takes place between Kirby's Dreamland 2 and 3 due to Dark Matter Blade being a clone based off of Dark Matter's "incomplete" form and Star Dream having no clue what its true form may be. Also, DM's introductory cutscene is titled "The Dark Rainbow Thief."
It's possible, although I do believe Dark Matter's true form is also in Dreamland 2. Although, that does give me the idea of making a potential timeline of Kirby games.
