Duff Race Car, Lemon Tree and Bridges?

Duff Race Car: Decoration given away leading up to the season opener. If you just started playing, you missed it (no biggie, just cosmetic, no bonus...not that they work anyway).

Lemon Tree: Won in a weekly box (probably have to wait until after Halloween since the current boxes only give treats, toilet paper, and eggs). Used to be able to steal from a "friend", haven't been able to steal them for awhile.

Bridges: Place water/river, build a road over it.
