In the midst of conversation with a friend we were discussing the act of setting nests in a row and then coaxing them to have a race to the home stump...then we had a thought...Meeroo race tracks! Something they could be set on and then triggered to run around, most likely one lap and the winning meeroo maybe wins a small amount of personal regard or a treasure for the owner. Also meeroo mazes. test the intellect of your fuzzball same principle applies they all start at a central location and have to find their way out. gaining small personal regard for winning or a treasure for the owner :)
