Coconut Grove how many wonders can one cavern hold?

Coconut, yes. Nodding, he confirmed when she repeated the name of the nut. Do you want to try it? They're quite delicious. Without the need for an answer, Heironymous already picked up the thing in his jaws and placed it down on a flat rock surface. Humming the same melody as before, he began to comb the beach in search of something... 

Once he found it, a large flat enough piece of sturdy wood, he placed it at the top of the brown nut, balancing it by pressing it with his nose, nudging in all directions until he was happy with it. Watch this. He said gleefully, eyes watching for her reaction while he himself pounced onto the plank perched on top of the nut. 

Under his weight the nut snapped after a couple of bounces, clear liquid oozed from the cracks and once he relieved the nut from his weight, it fell into two perfect halves. The water is sweet - eat only the white flesh.
