This is Gamemaxx, a gamepad controller capable of holding four litres of liquid. You can suck on it using a flexible tube as you play. The controller weighs 4kg, so it has a built-in neck strap. And a fan. It's what every serious console gamer would like under the tree.
It's just too bad it doesn't exist. The Gamemaxx is actually one of those prank boxes that are used to pack your real present. Available now at for $8 at Prank Pack.
