There are two versions of Kirby's Star Stacker: the original Game Boy release and an enhanced remake for the Super Famicom, often referred to as Kirby's Super Star Stacker. Both versions have tags, but they're seemingly used interchangeably. The regular Star Stacker tag is mainly used on art of Gryll, despite said character being exclusive to the remake. Meanwhile, the remake's tag only has four posts, two of which are large group images that include Gryll, and one of which seems to be a mistag (The only Star Stacker character I could spot in post #8070031 is Mr. Star, who's in both versions of the game.)
For all intents and purposes, there seems to be nothing differentiating these tags. At first I considered adding the Super Star Stacker tag to all Gryll posts and submitting a BUR to have the regular Star Stacker tag imply it, but after giving it some thought, I think it would be best to just merge the tags. Neither one has very many posts, and they're usually considered two versions of the same game anyway.
