walter More interactions while riding Wobi.

[Danila6300]

I've seen people suggest more than once that Walter be allowed to dig up dirt piles without getting off Woby, I think this could also be supplemented by allowing him to also open the umbralla dome without getting off Woby. I think in terms of interactions you can limit yourself to more than just piles of dirt and umbralla, you can throw in some additional ideas. 

The idea is to give Wobie his own advantages over Beefalo and make players think more about who they ride.
