The Ultra Stamp appears to be an oversized squeaky toy hammer with an ink tank formed from a white-capped plastic jug. Its handle is neon yellow, with the rim between the tank and mallet face on blue. The mallet face and ink tank change color with the user's ink. On the front of the mallet face is a pattern cropped from the SquidForce logo, which is also used as the Regular Battle logo. A white band around the handle has the Nouveau logo, while the ink tank has the Octopus Oil logo and the Nouveau logo.
The Ultra Stamp was announced on 29 October 2018. It was released on 7 November 2018 as part of Version 4.2.0. Preliminary versions of the weapon were found by data miners starting with Version 4.0.0, under the code name "SuperStamp".
When activated, the player holds a gigantic plastic mallet in front of them, which continuously stamps ink on the floor while running and provides almost total cover from the front while leaving the back exposed. Take note that in the few frames that the stamp is swinging in the air, the player is still vulnerable from the front and can be splatted. Pressing swings the mallet and strikes it on the floor, and holding it down lets the player move forward quickly while splatting enemies in the way. Turning is fairly slow in this state. In the air, players can press the attack button to swing the mallet once at high speed, which is a smaller yet fairly efficient attack for splatting opponents directly, while pressing throws the mallet and ends the special prematurely.
