Busted
This is a list of rumors and leaks that have been confirmed false.

Cheat code


Some days after the game's launch, players noticed that some Sunken Scrolls, as well as signs on Inkopolis Plaza, contain what appears to be arrows pointing up, down, left or right.

On the 2015-06-09, the official Splatoon Facebook page made a joke post referencing how some Facebook users accidentally type Google search queries on their Facebook profiles. This joke, however, sparked curiosity among fans, as the "search" was for "Squid Jump cheats". Naturally, Nintendo staff themselves would not be searching for cheat codes on a game made by their company, meaning the post was placed there on purpose, likely to hint players about the existence of a code hidden inside the game.

On top of this, the official Splatoon Tumblr account made a post about how players can press on the Plaza to look around, and how this serves the additional purpose of getting information on Miiverse posts. It also mentioned that it "may also have another use", which remains unknown to this day.

As of yet, no code has been found, and it is unknown if there is any relation between the arrows, the rumored code, and the rumored extra function of, or if any secret exists, to begin with. Players have since been attempting to figure something out by input the arrow's directions during different parts of the game, mostly the Squid Jump minigame, but without luck.

However, The Art of Splatoon definitely shows that it simply is a stylized spelling of "ブイヤベース" (Booyah Base) in Inkling.

Super Mario Sunshine DLC


There was a "leak" on the internet that Super Mario Sunshine amiibo DLC was coming to Splatoon. Only a single image existed regarding this supposed leak. It has since been proven fake, with the author of the leak releasing the images they used to create it.

New Super Mario Sunshine DLC
During July, a new Super Mario Sunshine amiibo DLC rumor with several images was found. These images supposedly depicted new Sunshine-related gear and Octo Valley missions. The supposed announcement date passed, and nothing like it was added, confirming it as false.
