...cleaned the greatest stables in the world in but a single day!

Find King Augeas. ASK AUGEAS STABLES.

Find three boulders:

• one south of Chiron
• one in the Forbidding Hills
• one boulder at Foot of a Cliff, near Thespiae

Find River Erymanthus, two south and all the way west of Chiron.
PUT BOULDER RIVER three times. Return to King Augeas, go one north and PUNCH WALL. The stables flood and are cleaned.

BEWARE: The king is agg to you now for nearly drowning his horses! Go N to avoid the king

The PUNCH WALL step requires a strength over 45 (unsure of actual minimum, only that I couldn't meet it)
