Easter eggs

The following is a list of Easter eggs and secrets in Splatoon.

Basketball
On the testing area that can be accessed by pressing Y on the equipment screen, there is a basketball hoop. If the player tosses a grenade and it goes through the hoop, their Inkling will say a celebration, much like they would if they were to splat an opponent in Turf War.

Blooper and Octorok
Hidden in various areas such as Zone 4 are stickers featuring the Blooper from Super Mario Bros. Series and the Octorok from The Legend of Zelda Series

Sea Scroll flipbook
Each Sea Scroll has a doodle of a character on the bottom right corner. By flipping through the pages, one can see a flipbook-like animation showing the character flip around twice and turn into different ones. It starts off with the Zapfish, then changes to Judd, and finally, to Sheldon.

Squid Sister wave
To the left of the Dojo on Inkopolis Plaza, there is a studio where the Squid Sisters can be found chatting. By staying near the window and using the first person view with ZR, the sisters will eventually wave at the player.
