Also when they try to bring him to the doctor he refuses to treat him because they have no money.
Kino had been diving for pearls to try to get money for Coyotito's treatment from when he had been stung by a scorpion when he had found a huge pearl from rge ocean floor but after they do everyone finds out and then Kino and Juana have to fight off thieves and robbers to keep the pearl safe for their future as the greed for the pearl becomes unbearable.
After Kino ends up killing a guy over the pearl he decides him and his family will escape to the mountains to get to the capital to sell the pearl which there then they all get chased by trackers and escape into a cave but when Kino tries to attack them they think his baby coyotito is a coyote so they shoot up in the cave to scare it which then coyotito KIno and juana's baby gets shot as a result.
As they carry their dead child Coyotito they return to the town back from the mountains everyone stares at them and the whole down stops as they walk down to the beach so Kino takes the pearl with Juana then throws it as far into the ocean as he can.
