Mer-Boy is depressed that while other youths in his village have regular relationships he must forever be second place in Wonder Girl's life, especially since no man can set foot on Paradise Island. Attempting to get her attention he feigns being injured until Wonder Girl comes to his rescue. He reveals his ruse and get nothing but her anger in return as she flies off, making him wonder what he did wrong. When she goes to her mother Queen Hippolyta for advice, the queen tells Wonder Girl that the boy merely acts out foolishly because he cares for her and that she should be more sympathetic toward him. She decides to give this a shot and when Mer-Boy sends her a message asking her to come to a dance, she accepts and gets dressed up for the occasion. However when she accompanies Mer-boy to the dance, Diana becomes instantly jealous when Mer-Boy shows more attention toward a female mergirl named Firra and storms off. When Mer-Boy attempts to explain things, she refuses to listen and clamps him in a giant clam before swimming off. Firra, being only friends with Mer-Boy, hears about what happens and tries to explain to Mer-Boy that women get jealous and that she'll eventually get over it if he gets her something special. However, Mer-Boy takes this too far and goes to collect the rarest item in the land: The sea spider necklace for Wonder Girl. Hearing about this, and knowing such a trip would be dangerous, Firra goes to Paradise Island and explains everything to Wonder Girl. Worried for Mer-Boy, Wonder Girl swims to the sea-spiders lair and finds Mer-Boy caught in the aquatic-arachnids web. She frees him and gets the sea-spider caught up in it's own web. When they are swimming away Mer-Boy laments that he failed in getting her his present, but Wonder Girl tells him that he's won her favor again and kisses him on the cheek.
