I was wondering about those brown turds too? :rotf:
Is them brown things to make it rain.
You drop one on the ground, run around it twice from north to east, and then stomp on it 3 times, yelling rain,rain,rain.
When one is interested in PC stuff the best thing to do is find as many PC examples of the thing you and and use them as guidlines....probably will not find to many sandwiches in the originals :idunno:
