Save the Crab! (カニを助けよう！, Kani o Tasukeyou!, lit. Help the Crab!) is an event in Tomba! 2: The Evil Swine Return. This is one of the first primary events in the game. This event introduces a new character that will appear several times in the game.
Save the Golden Crab from the fire.
This event is activated directly after the Go to the Burning House! event. After Tomba has obtained the bucket from the previous event, fill it with water by collecting water drops that comes out of the water faucets. Active them by lowering the seesaw to the left of the faucet.
Head to the old man's house and give him the water-filled bucket by selecting the bucket via the Adventure Journal. A short cutscene will play and he wants another bucket of water. Get some more water and give him the second bucket of water, and he will extinguish the fire. The event is cleared.
