It was a calm and peaceful day on the merry. Zoro was asleep, Usopp was telling a lie to Chopper, Sanji was cooking, Nami and Vivi were picking tangerines and Luffy was sitting on his special place on the merry's head. That is until Nami looked up from picking her tangerines and spotted an island.

"Oi, Luffy island dead ahead. Are we stop?" Nami said as she picked another tangerine.

"Let's go!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! How long until we get there Nami?" Luffy asked with a wide grin.

"It will be one hour Luffy." Nami said with a smile. "We're going to stock up on supplies."

"OK it sounds fun." Luffy said

"Nami lets get these tangerines to Sanji." Vivi said.

ONE HOUR LATER

"Cool" Luffy said with stars in his eyes. "It's awesome"

They had made it to the island and it was so beautiful. The houses were all sorts of colors golden yellow, peach orange, sky blue, lime green and many more colors. The town looked like it was celebrating something or it was having a festival. There was lots of stores opened some were small some were huge!!!!!!!!!! Luffy, Usopp and Chopper ran off to go explore the island.

Nami sighed out of frustration "I guess we'll split up then Sanji go find some food Zoro guard the ship."

"No! I going to find some place to go fix up my swords." Zoro said as he walked away

"BUT WHO IS GOING TO GUARD THE SHIP?" Nami yelled at him.

"Me and Karue will guard the ship." Vivi said as she smiled at Nami.

"Ok, are you sure?" Nami asked.

"Yeah, it'll be ok." Vivi insisted

"Well ok then lets go." Nami said

Later in the after noon Nami was looking through all the stores. Then she came up to this tent. It was purple with gold streaks on it. She said she would just take a peek inside the tent so she walked in. She saw shelves with bottles on them. Then she saw a table with a crystal ball on it. Nami thought it would be stupid so she turned to leave but she was stopped by a mysterious woman. She was wearing a big hat with three peacock feathers on it and a long purple dress with looked like it had jewels on it. Rubies, emeralds, diamonds and tons more jewels. Nami eyes lit up from the beauty of the jewels.

"My I help you?" The 42 year old woman said as she started to dance around the room with delight. "A costumer what is your name young lady?"

"What?" Nami said as she snapped back to reality. "Oh, my name is Nami, and yours?"

"My name is Madam Lulu. Welcome to MADAM LULU'S TENT OF MYSTERY!!!!!! How may I help you?" Lulu said still dancing across the room.

"Oh I was just about to leave sorry if I caused an trouble." Nami said as she walked towards the exit. "Bye."

"No you can't leave!!!!!!!!!" Lulu said as she grabbed Nami by the arm. "I mean,may I interest you by telling you your fortune?"

"No thank you." Nami said as she tried to leave. "I've got to go."

"Then may I interest you in a potion?" Lulu said with a wicked smirk. "It has mystical magical affects on your age."

Nami stopped struggling for a minute. "What kind of effects?" Nami said as she raised an eyebrow. 'I guess I could listen for a second' Nami thought.

"It makes you look and feel younger than you are. It works like a charm." Lulu said as her smirk got bigger. "Would you like to by a bottle?"

"Hmmmm. Ok how much?" Nami said about to make a deal.

"200 berries, but for you 100."Lulu said

"10"

"90"

"20"

"80 and that's the lowest I'm going." Lulu said as she turned here head.

"Fine I guess I'll just leave then." Nami said as she turned. She was going to get that potion no matter what.

"Fine 50 and that's the lowest!!!!" Lulu said

"You got a deal Lulu" Nami said as she took 50 berries out of her pocket. She said her good byes to her money and handed it over. Lulu gave her a tall curvy bottle with light blue liquid in it. "Sucker." Lulu whispered to herself.

"What?" Nami said as she lifted an eyebrow.

"Nothing, nothing enjoy your new potion." Lulu said

After that Nami couldn't wait to get back and try out her potion. When she made it back to the ship all the crew was there surprisingly.

"Luffy you don't go around punching people." Usopp said as he scolded Luffy

"That guy had it coming." Luffy said with a pout. Apparently Luffy got into another fight. But Nami didn't care. She started walking to her room. Then chopper came in front of her. "What do you got Nami?" he asked. Then they all stopped what they were doing and looked at Nami

"Nothing go away!!!" Nami said. She was getting mad.

"Nami-swan I missed you so much!" Sanji said with a hearts in his eyes.

"Love-cook" Zoro muttered to himself. Sanji ran up to Zoro and kicked him in the face.

"Het I wanna fight to." Luffy said as he ran up to go join the fight. Nami just ignored them and tried to make a move to her room but forgot Chopper was infront of her. Then she tripped as the bottle flew out of her hands. Then her eyes widened. The potion cost a lot money. Then crash the potion had broken and the blue mysterious liquid had come out and it laned on Zoro, Luffy and Sanji.

Luffy looked up and it seemed like everyone had grow. His head hurt and he did not know why. He turned and saw Sanji and Zoro were about 4-years-old. Then he noticed something was wrong. He felt shorter and weaker.

"What happened?" He asked in a much higher pitched voice then he normally would. Then he used all of his brain power to think and realized that he must be at least 2-years-old.
