Dolphin Tale

S1 E6: Zac is still enjoying being a merman and the mermaids are no closer to removing his powers. Lyla believes they need a new strategy - maybe they should become his friend so they can convince him to lose his powers. But Nixie doesn't think Lyla is capable of making friends - she can't even make friends with a dolphin! Unfortunately for Lyla she never learnt to speak dolphin, one of the perks of being a mermaid, and Sirena and Nixie love to make fun of it. But the young mermaids decide to give 'friendship' a try and head to the Ocean Café to find Zac. While Lyla and Sirena follow Zac home to try to get his trust, Nixie decides they are not going to succeed and goes for a swim. David's brother Joe, who delivers seafood to the Ocean Café, has a new boat and takes David out for a spin to show it off. While speeding around on the Broadwater, the boat's fish-finder locates a dolphin... but it's not like any dolphin Joe has seen before and he decides to chase it, while refusing to listen to David's protests. And it's not a dolphin, but Nixie out having fun with dolphins. With Joe closing in, Nixie panics and gets trapped in some netting under the jetty outside Zac's house. Under the impression that Joe is terrorising a dolphin, Zac subtly uses his powers to interfere with Joe's boat, and Lyla secretly uses her powers to help. With everyone distracted, Sirena frees Nixie from the netting and they escape to safety. Back at the café, there's celebrations for teaching Joe a lesson... and the mermaids are on their way to becoming Zac's friends.
