- Kneaded eraser

Now in the game are 4 total skins. The original, pink, folding and kneaded eraser!

The first upgrade makes you get better chances at gaining coins, the coin generation changes from 1/10 to 1/5. The buddy upgrade 1 is that the buddies time until no use cooldown is more and the second upgrade gives him more use before he vanishes.
