Before they arrive at Fred's house Nemo asked him if he would help him rescue the fish from the tank he had been in earlier. Fred, of course, wanted to seem like a good person, so he said yes.Fred and Nemo swim back to the fish tank. Nemo, using the tube that connects the ocean and tank, swims back into the tank and gathers everybody and tells them the good news. One by one they go through the tube, when everybody has safely made it to the ocean they thank Nemo and Fred for helping and all swim their own ways to their homes.
