Around here you can buy 'top soil' by the bushel basket, used for small garden fixin's, or by the truck load to be used by landscapers to repair or construct new lawns. It's all sifted and air fluffed. Easy to work with. A 'field load' of the black stuff is also used in new lawn construction, and comes by the truck load with huge chunks of the stuff to be spread by a bulldozer. This black dirt would really stand out in a set that is made in brown clay or sandy soil. Not sure what the piglet bought. Better ask, huh.
