Awesomenauts update, which is now live on Steam. Well, technically it's not a Creeper, but rather a Creeper skin for existing 'naut Clunk. Still, creepers shouldn't have a role model like this to look up to.
The Creeper Clunk skin can only be acquired by finding someone wearing it in-game and killing them, thus becoming "infected" with it. Since the skin can't be bought or obtained otherwise, we expect that equipping it will be somewhat akin to painting a giant bullseye on your chest. Which is how it should be, honestly, since all Creepers deserve to die.
All Creepers deserve to die.
