Sonic, Merna and the Chaotix were sailing across the ocean, looking for the pirate ship on which Tails, Knuckles and Amy were being held captive. Sonic was looking around, feeling a little seasick. Fortunately, Merna was standing next to him, making him feel less seasick.
'Seen anything yet, Sonic?' Vector asked Sonic.
'Not really.' He responded.
Charmy was looking through binoculars to find the ship. Suddenly, he saw it.
'Ship ahoy!' Charmy exclaimed! The rest saw the ship as well.
'Good! Sonic, Espio, Charmy, you guys go deal with those pirates! I'll keep the ship moving and I'll protect Merna at the same time!' Vector said.
Sonic, Espio and Charmy nodded and once their ship got close enough, they jumped onto the pirate ship and started fighting the pirates. Charmy stung some pirates with his angler and Espio attacked them with his shuriken. Sonic Homing Attacked the pirates and kicked them as well. Once all pirates were defeated, Espio ran up to the pirate ship wheel to keep the ship from tipping over. Sonic and Charmy went down deck and found Tails, Knuckles and Amy there, along with a bunch of treasure.
'Sonic! You're alive!' Tails said.
'I knew it all along. You always come back from a fight.' Knuckles said with a grin on his face.
'I'm so glad you're okay!' Amy said.
Sonic and Charmy untied Tails, Knuckles and Amy. 'Could you take as much treasure as you can carry with you? I promised Vector he'd get it for helping me find you.' Sonic said.
'Sure.' The three of them said. Grabbing as much treasure as they could, they went back to the upper deck and stepped onto the Chaotix' ship. Vector was happy to see all the treasure.
'Thank you!' Vector said, smiling.
'No problem, Vec.' Sonic chuckled. Tails noticed Merna. 'Hey, aren't you Merna?' He asked.
'Yes, I am. You're Tails, right?' Merna said.
'Yeah. How did you become a normal hedgehog?' Tails asked.
'I'm wearing magic pants that give me legs.' She explained.
'Ah, I see.' Tails said.
'You know this girl?' Knuckles asked.
'Yeah, Sonic and I met her back when it was just the two of us.' Tails explained.
'That's so cool!' Amy said.
'If you don't mind, I'm piloting the pirate ship back to Port Sunshine!' Espio shouted.
'That's fine!' Vector shouted back. Vector then started sailing back to Port Sunshine, with Espio piloting the pirate ship behind. As they were sailing, Sonic and Tails told Knuckles and Amy about how they met Merna and the adventure they had with her. Amy had a glimmer of jealousy but hid it. Once they got back to Port Sunshine, Sonic thanked the Chaotix for their help, and then went to the beach with Tails, Knuckles, Merna and Amy.
'Merna gave me a necklace that can turn me into a Merhog. Whenever I'm in my Merhog form, I'm not afraid of water.' Sonic said.
'That's great to hear.' Tails said, smiling.
'Can we see your Merhog form?' Knuckles asked out of curiosity.
'Sure.' Sonic said. He ran into the ocean, put on the necklace and dove under the water. Soon after, he jumped back up, showing blue fishtail. He then dove back into the water. Sonic's friends were amazed at Sonic's Merhog form. They ran into the water to get a closer look at Sonic's Merhog form.
'This looks so cool!' Tails said.
'That looks epic!' Knuckles added.
'You look even hotter as a Merhog!' Amy squealed.
'Well, Merna and I will be going to Mertopia now. I'm gonna be there for a while, and I'll be occasionally coming back up here.' Sonic said.
'Okay, be safe.' Tails said.
'I will.' Sonic said.
'See you again soon.' Knuckles said.
'You too, Knucklehead.' Sonic said.
'Come back soon, Sonic.' Amy said.
'Okay, Ames. See you guys soon!' Sonic said. Merna took off her magic pants and regained her fishtail. She and Sonic then dove under the water and swam off.
