Filthy sock puppet
From Twilight Heroes Wiki
filthy sock puppet
Plural: filthy sock puppets
Hey! Some real grouch has apparently thrown away a perfectly good sock puppet. It's a little dirty now from all the time it spent in the trash, but it's still plenty good for having fun. For instance, you could use it to mock your opponents and say you didn't do it. Or, um, well, I'm not sure what else. Holding your hand up all the time to talk to it will probably make you a little bit stronger, I guess.
