i thought wolfgang was invincible while changing up or down forms? if that's only in the base game can you let Wolfgang move during them.
If you dislike the idea of him flexing while moving you can change his flex to the Usain Bolt bolt when running up or down, and the moonwalk when going sideways. and his wimp out, to old man hobble for left and right, and clutch stomach for down and i can't think of anything for up.
