Mermaid's Tear is a beautiful pink pearl that lays in the bottom of a deep ocean crevice a few miles from Kame House. Turtle tells Krillin that if he wants to prove his love to Maron, that he should go find and bring her the Mermaid's Tear.

When he and Gohan do find it, many fish and other sea creatures heavily guard it, so Krillin and Gohan leave it be and return to Kame House, specifically because they do not wish to kill off the fish to get it as they would be no different than the Ginyu Force with the Dragon Balls on Namek.
