1. First, the player needs to go into the water, and then pick up the stone in the water and aim at the crab that jumps up.
2. Note that these crabs will jump towards the player, and they will lose blood when they encounter the player, so you need to pay attention to avoid them.
3. Then the player can get the crab after smashing it to death. Note that the crab has a name, importance and star rating.
4. In the end, just hit the crab with this stone. Then players should seize the time to catch it after learning it.
