I don't know if anyone else has already done this, but a few days ago I completed the mulch quest quiz. :) I thought it was challenging, so I'm posting it. The sad thing is that it's hard to do, but you only get 20 coins as a reward. And you payed a coin to play so you only really win 19 coins. Anyway here is a pic.
Atleast now I know more about recycling and pollution and all that jazz.
