Kinnow Island

Ash and the gang relaxed on a beach located on Kinnow Island. It had been a hectic two weeks for them. First they had visited Pinkan Island. It was given that name because there were these fruit trees that bore special pink berries that would turn a Pokemon pink. Pikachu tried a pink berry and his tail changed color. Next they visited a stage boat. Instead of people acting in stage shows, it was Pokemon doing all the acting. The clever thing was that the Pokemon did all the talking and dancing. Of course the Pokemon couldn't really talk; it was human actors acting out their voices from backstage, while the Pokemon just mimed the voices. Ash and the gang found that out after they saw a performance and promised to keep it all a secret.
Ash and Tomo were playing with Pikachu and Growlithe in the sand and Tracey was sketching in his paper pad. Meanwhile Misty was training her Pokemon. Right now she was training her Psyduck and Goldeen. Psyduck was practicing it's Water Gun attack.
"Your Psyduck is going well Misty." Ash said. 
"You're right Ash." Misty said with a smile. "Thank you for helping me teach Psyduck Calm Mind."
She remembered that Ash's Psyduck turned out to be a real fighter before it evolved into Golduck, because the move Calm Mind helped Psyduck become a great fighter. So Misty decided to have her Psyduck learn Calm Mind to help it become a great fighter. 
"Ash told me that both of you have a Golduck." Tracey said.
"That's correct." Misty nodded. "My Golduck is back at the Cerulean Gym."
"I'd like to visit your gym someday Misty." Tracey said.
Just then another Psyduck popped out of the ocean.
"Where did that come from?" Misty asked.
"Sorry that Psyduck is mine." A voice said. 
The voice belonged to a girl with a blue hair.
"My name is Marina." She said. "And I'm a water Pokemon trainer."
"What a coincidence." Misty said. "I'm Misty and I'm a water Pokemon trainer too."
"Really?" Marina said. "Do you love water type Pokemon?"
"Yes I do." Misty answered. 
Misty and Marina began chatting away about their admiration of water type Pokemon. 
"Those two sure love water type Pokemon." Tracey said. 
"I feel bored listening to this." Tomo sighed.
"Hey I know, let's have a water Pokemon battle." Marina suggested.
"Sounds good." Misty agreed, liking the idea.
Marina and Misty stood on two big stones at platforms while the battlefield was the ocean. Marina sent out her Tentacruel, while Misty sent out her Goldeen.
"Wow Misty, your Goldeen is gorgeous." Marina said.
"And your Tentacruel is charming Marina." Misty replied.
"This is going to last all day." Ash sighed.
"Tentacruel, use Wrap on Goldeen." Marina ordered. 
"Quick Goldeen, Agility." Misty said.
Thanks to Agility, Goldeen managed to dodge Tentacruel's tentacles. 
"Now use Supersonic." Misty told Goldeen.
Goldeen's horn glowed a light blue and released some blue circles that headed straight towards Tentacruel which caused it to become confused. 
"Now use Horn Attack." Goldeen hit Tentacruel with it's sharp horn, causing it pain. 
Marina was getting worried.
"Tentacruel, Poison Sting!" Tentacruel fired some purple spikes from it's mouth which hit Goldeen causing it to faint.
"Goldeen return." Misty said, returning it to it's Poke Ball. 
Misty sent out Staryu. 
"Tentacruel, Poison Sting again." Marina ordered.
"Staryu, Swift." Misty said.
Staryu fired stars from it's jewel and the stars broke the poison spikes striking Tentacruel, causing it to faint. Marina sent out her Psyduck. 
"Water Gun." Misty ordered. 
"Confusion." Marina said.
Psyduck's eyes glowed blue and it's power made the Water Gun hit Staryu instead, causing it to faint. Misty called out her Psyduck to battle Marina's Psyduck.
Suddenly a blue duck popped out of the ocean.
"Hey it's a Golduck." Misty said. Marina squealed.
"Golduck's my favorite water type Pokemon. I'm going to catch it."
"Psyduck, can you use Scratch on Golduck?" She asked. Golduck winced a bit.
"Now use Confusion." Psyduck's eyes glowed blue and it lifted Golduck into the air.
Marina tossed an empty Poke Ball and caught the Golduck. Marina squealed in delight, happy to have caught it.
"Congratulations Marina." Misty said. "Shall we continue our battle?" 
"Yes, let's." Marina said.
In the end it was a draw. Misty's Psyduck and Marina's Psyduck fought well against each other and both of them fainted at the same time.
After the battle it was time for the gang to leave Kinnow Island. 
"Thanks for the battle Misty." Marina said. 
"You too Marina." Misty replied. "And good luck with your new Golduck."
So after bidding farewell to Marina, the gang left on Lapras.
