On Indonesia's idyllic island of Bali, the boys seek two stinger sin the water. In the shallow lives the insectivore rove beetle, whose sting terrorizes them way beyond what they expected from such a small critter. In the ocean lives the truly redoubtable sea urchin,several of whose spines are generally triggered together at contact, so they each press on an arm, and find its reputation for devilish pain deserved.
