Sniff and Scurry, used the simple trial-and-error method of finding cheese. They ran down one corridor, and if it proved empty, they turned and ran down another. They remembered the corridors that held no cheese and quickly went into new areas. Sniff would smell out the general direction of the cheese, using his great nose, and Scurry would race ahead. They got lost, as you might expect, went off in the wrong direction and often bumped into walls. But after a while, they found their way.
