I have a few sugjestions.
1. penguin style player, a short chuby penguin and what ever color your body is is the color of the black part of the penguin.
2. item penguin smoothie, a smoothie with a penguin head for the lid and a straw in it you click with it and it makes a drinking sound but the cup stays and it will be empty then you can hold down the mouse and through it as a weapon.
3. penguin grenade, you get the idea but the explosoin is icy.
P.S. I am obsesed with penguins!
