Calamar Macawker Quest

Here are the two dig spots.

The first one requires a party of 3 people. Each of you need to dig on this spot I'm sitting on (-3,-8).
Once you've dug your way into the secret entrance (cache 22), simultaneously stand on tiles and hit the switch to enter.



And this second one requires a party of 6 people. Again, everyone must dig on the spot I'm sitting on (0,-4).
Once you enter, stand on all of the tiles to enter. You will be fighting waves of lv.50ish enemies in this section.
