An adult monkey huddled two babies one on each site. The youngster on the right was visibly shaking in the cold. Most of the time they buried their face into the chest of the adult monkey in the center and even the adult lowered his face down and the three formed a fairly big furry ball. But from time to time, being monkeys and curious, they lifted up their head to see what's going on out there.

This while a lot of monkeys were taking a dip in the hot spring pool? What gives? Well, the three here apparently do not belong to the aggresive clan that controls the pool. If they try to go in, they may get attacked. So, they stay close to the pool's edge to still get some warmth coming from the pool.
