WarioWare: Get it Together![]
September 10, 2021
Splatoon
Wario
One of 9-Volt's microgames is based on Splatoon 2. It specifically shows the end of a Turf War with Judd and Li'l Judd tallying the results and the player must stand in front of the side of the team that inked the most turf based on the image on the background. After a while the percentages of covered turf is revealed and if the player guessed correctly the microgame is won.
The stages are The Reef in Level 1, Sturgeon Shipyard in Level 2, and Humpback Pump Track in Level 3, with the Turf War results being closer at higher levels.
Note that the plot of Get It Together! involves the protagonists being sucked into the games and they then directly interact with them, so in this case the microgames generally create an in-universe link, however in this specific microgame the characters only stand in front of the result screen without any real interaction, so this is considered an arguable link.
