Rinelo Island

While on the way to Pummelo Island, Ash and his friends stopped on Rinelo Island. In addition to taking a break there, Ash saw this as a opportunity to train his Pokemon before the Orange League competition. Of course he didn't know what Pokemon the leader of the Orange League would use, so he decided to train his Pokemon and himself to prepare for it. Right now he was jogging with Tomo, Pikachu and Growlithe. Misty was fishing in the stream, to see if she could catch more water type Pokemon. And Tracey was sketching a wild Vileplume. 
Right now the day was progressing well, but that would soon change. Tomo accidentally ran into another wild Vileplume and that made the Vileplume angry. Ash and Tomo tried to apologize to Vileplume and explain it was an accident, but it wouldn't listen. In anger Vileplume fired Stun Spore at them, paralyzing Ash and Tomo. Pikachu and Growlithe weren't hit by the Stun Spore. They ran to Tracey for help and when he saw the paralyzed brothers he brought them to the cabin they were staying in. The wild Vileplume Tracey had sketched felt sorry for Ash and Tomo and offered to help Tracey who accepted it's assistance.
Soon Ash and Tomo were laying in the cabin beds as Tracey and Misty took care of them.
"What can we do Tracey?" Misty asked. "We don't have any medicine for Ash and Tomo and we're nowhere near a Pokemon Center." 
Tracey thought for a moment. 
"There is something we can do." He said. "We need to gather salveyo weed."
He borrowed Ash's Pokedex to show Misty what salveyo weed looked like.
"This plant can cure paralysis." 
"It says on the Pokedex that Poliwag feed on it." Misty said. "And the good news is I have my two Poliwag with me."
So Misty and Togepi left the cabin to look for the salveyo weed leaving Tracey, Vileplume, Pikachu and Growlithe to take care of Ash and Tomo.
Misty went to the lake she had been fishing at earlier and released her Poliwag.
"Okay Poliwag." She said. "I need you to find me some salveyo weed please."
Misty's Poliwag's jumped into the lake and swam to the bottom to get the salveyo weed. They found it with very little trouble and brought it to Misty.
"Thanks you two." She said. "Now to take this to Tracey."
Misty returned her Poliwag and was just about to head back to the cabin when she saw something by the lake. A pink Pokemon with a big shell thing on it's head was panting heavily by the lake. 
"No way." Misty gasped. "It's a Slowking."
She remembered the time the gang met a Slowking. When Misty looked at the Slowking, she saw that it had been paralyzed.
"It must have been hit by Vileplume's Stun Spore too." She said to Togepi.
Misty used a Poke Ball to catch Slowking since she couldn't carry the salveyo weed and Slowking at the same time.
Soon Misty was back at the cabin and gave the salveyo weed to Tracey showing him Slowking too. Tracey used the weed to make the medicine at once. Then he gave it to Ash, Tomo and Slowking. Soon all three were cured of their paralysis. 
"Thanks Tracey, Misty." Ash said. 
"Thank you." Tomo repeated.
Slowking thanked Misty and Tracey too.
"Well I'm certainly glad you three are all right now." Tracey said. "Just try not to run into anymore wild Vileplume." 
Ash and Tomo agreed; they didn't want to be paralyzed again. 
Misty walked up to Slowking.
"Hey Slowking." She said. "If it's okay with you I would love to have you as my Pokemon."
Slowking smiled, showing it wanted to stay with Misty.
Ash looked it up on the Pokedex.
"Slowking, the Royal Pokemon and a evolved form of Slowpoke. It has incredible intellect and intuition. Whatever the situation, it remains calm and collected."
"You know I think Slowpoke's evolution line is really strange." Ash said. "I mean Slowpoke evolves into Slowbro when bitten on the tail by Shellder and Slowpoke will only evolve into Slowking when wearing a King's Rock and then being bitten on the head by a Shellder." 
"A Pokemon's evolution is always full of mysteries Ash." Tracey said. "And it shows how Pokemon can be truly amazing."
Ash, Tomo and Misty agreed with him.
Just as the gang was getting ready to leave the cabin and head to Pummelo Island Tracey told the wild Vileplume that it could go back to the forest. But Vileplume didn't want to; it wanted to stay with Tracey. So Tracey caught Vileplume. Then the gang set off to Pummelo Island with Slowking and Vileplume in tow.
