Yugi was currently at the student cafeteria eating his breakfast, "Yami and I met in the past? No way...how come I don't remember?" Yugi sighed, the whole night he had tried to remember when he had met Yami but nothing came up.

Joey and Kaiba also noticed Yugi looking a bit distracted, "Yugi looks dazed" Kaiba said holding a cup of coffee in his hand.

Joey was happily munching his food, "I wonder what happened?"

"Let me ask you guys, do you remember anything that happened when you were three?" Yugi curiously asked his friends.

"Three?" Kaiba asked.

"Why do you ask?" Joey added, really confused on why Yugi was so distracted.

"Yami said that he knew me when I was three..." Yugi explained remembering what had happen this morning.

"We met when you were three. Normal people should have some memories of when they were three right?" Yami asked and Yugi was scratching his head thinking hard.

"But I can't remember a thing..." Yugi cried out in distress. Kaiba and Joey both pity Yami.

"Joey, you grew up with Yami, do you know anything?" Kaiba asked and Joey shook his head looking completely clueless.

"Never heard anything about it"

"They both have no idea..." Yugi thought.

Kaiba was in his thinking mood, "At a time like this, if only we had that..." Joey and Yugi were watching Kaiba inquisitively wondering what he was going to do when he pulled out a book from his bag.

'Unbelievably Amazing Mushroom Encyclopedia'

Yugi who was holding the book looked at Kaiba oddly, "Kaiba you carry this kind of stuff around...?"

Kaiba chuckled, "Nope, I was just about to return it to the library, and so I have it with me." He took the book off Yugi and begin to flip through the pages, "Hmm...I remember it's somewhere here...ah, here it is."

Memory Mushroom- After eating it, you will be able to remember things from your past. Just recite what you want to recall while eating it. Can be eaten raw.

"Where can I find it?" Yugi asked and Joey uneasily smiled.

"Read on"

Yugi disappointedly walked along the forest with Fluffy following him.

This is a rare species of magical mushroom, and it seldom grows in the wild.

"Such a useful thing, how can it possibly grow anywhere along the road...?" Yugi gloomily thought and he looked up ahead to see a whole bunch of memory mushrooms under the big giant oak tree. "I found it! The memory mushroom...! That's the exact pattern, so much for being rare; it was just growing by the roadside..." Yugi pulled one off, "The book mentioned that it can be eaten raw...okay, I shall..." Yugi took a big bite, "Three years old, three years old..." Fluffy looked at him agitatedly.

"YUG!" Joey shouted and spotted his friend squatting down near a tree, "Why are you squatting there? It's time to go back to class..." Yugi didn't replied, "...Yugi?" Joey turned Yugi around and saw Yugi sitting there with tears rolling down his face.

"My mommy is missing..." Yugi wailed and Joey was taken aback by his friend's reaction.

"Could he have eaten the imitation?" Joey panicking thought.

Imitation Memory Mushroom- It looks exactly like the memory mushroom, except that the swirl is in the opposite direction. After eating it, you will not regain your memory. However, you will turn into the age you are thinking of. Just to add: The genuine memory mushroom is very rare. While the imitation can be found anywhere along the roadside.

"Oh no! I must inform Yami quickly..." Joey tried to sprint off when Yugi grabbed a hold of his tie.

"Oni-chan don't go..." Yugi said with teary eyes.

Joey could feel himself getting hot, "Yug...don't rub your body against Oni-chan otherwise..." Joey transforms into his monster self and picked up Yugi, "Oni-chan will turn into a wild wolf..."

Yugi laughed and clapped his hands, "Woof, woof!" He cheered and Joey has sweats pouring down his face, he did not like where this was leading.

"What are you two doing?" Kaiba asked when he had found the two. Joey was on his knee with Yugi sitting on his back.

"Kaiba! Help me...I have become Yug's dog."

Kaiba noticed the imitation mushrooms found on the ground, "Ah...he ate the imitation mushroom...but the effects should be gone in a few hours." Kaiba explained watching Yugi sucking his thumb.

"One-chan?" Yugi pointed at Kaiba.

"No, I am Oni-chan, just a bit more handsome" Kaiba explained and Joey smacked his head.

"WHAT? YUGI ATE THE IMITATION MEMORY MUSHROOM!" Everyone in the class exclaimed in surprised. And there were a big discussion going around the class.

"How old is he now?"

"Yugi, how old are you?"

"Three" Yugi said and holding onto Kaiba very tightly who was carrying him.

"Okay, okay, that's enough" Joey ordered trying to back the others away.

"Three? So young..."

"Stop it, can't you see that he's scared?"

"Although I hate kids, this is a chance to increase my popularity!" Vivian thought and said in her best sweet voice, "Yugi, come over to One-chan!"

Yugi cried and grabbed onto Kaiba's shoulder, "Her eyes are so scary!" He wailed and Vivian was fuming, her plan backfired.

"Children are so honest..." The rest of the student thought.

Duke smiled holding out a lollypop, "Yugi, do you want a lollipop?"

"Yes! Yes!" Yugi happily cried trying to reach for it but Duke was actually teasing him.

"Hmph! I won't give it to you..." With that he ended up getting bashed by his classmates.

"Hey! He's only three!"

"Don't bully him!"

"Here you go" Kaiba handed Yugi the lollypop who happily accepted it.

"What? Moto ate the imitation memory mushroom?" Kamako Sensei asked in a surprised tone.

"Transv..." Kaiba and Joey dragged Yugi back covering his mouth.

"Shh! Yugi!" Everyone whispered and Kamako Sensei had a question mark on her head. All a sudden the door opened and Yugi curious look at who was coming in. Yami's eyes widen to see Yugi standing looking dazed with a lollypop in his hand.

"Why are you in a daze? And holding a lollypop, you're not a three-year-old kid" Yami said in a strict tone and Yugi started crying which shocked Yami.

"Yami, you're too much!" Everyone shouted at him.

"Ah? I'm too much?" Yami was clueless, what the hell was going on?

Kaiba timidly smiled, "The story goes like this..."

Yami grumpily sat on his desk, "Three years old..." He crabbily thought with his arms crossed and Yugi was sitting beside him licking the lollipop.

"Let's begin our lesson." The sensei announced.

Yugi stopped his action and stared at Yami who felt his heart racing from Yugi's staring. Yugi got out of his seat and slowly skipped to the front classroom. "Ah, Yugi?" Yami was confused on what Yugi was planning to do.

Everyone in the class was also interested on knowing what the little boy was planning to do. Yugi stood up on top of the sensei's desk, "Yugi?"

"Show you my undies!" Yugi exclaimed pulling his pants down and everyone was traumatized by the sight. Kamako sensei dropped her books.

"YUGI! You can only do that in front of me! Yami shouted slamming his fist on the desk, "Sensei! I will have a make-up lesson" Yami replied and he grabbed Yugi by the waist with his pants back on, "I need to be a nanny for the day and look after this kid!" And he flew out the window.

"Does he know how to look after a kid?"

"No idea."

"Too much...No idea how your parents taught you, showing off your undies...must be that father of yours who taught you that right?" Yami grumbled to himself as he flew higher up in the sky with Yugi in his arms.

"So high, so high!" Yugi cheered with a big smile on his face.

Yami was stunned, "Yugi, you're not afraid of heights?" He recalled Yugi never really like flying before.

"I like it. It feels great..." He replied with smiling eyes.

"Yugi...when did you forget how to fly?"Yami thought and his concentration broke when Yugi started to squirm around.

"Pee..."

"Ah?"

"Pee pee"

"WHAT?" Yami shouted and Yugi squirm around even more, "Ah! No! Don't pee here! Hold it!"

"I need to pee!"

The night sets...

Yami was sitting on his bed feeling exhausted, "I ended up taking care of the kid for the whole day..." Yami heard the door creak and he looked up to see Yugi standing there with his big chibi eyes staring at him, holding his blanket, "Yugi, what is it? Didn't you just go to the toilet?"

"Daddy and mommy are not here..." Yugi bit his lip and tears were forming in his eyes, "They don't want me anymore..."

Yami slowly lifted up one of his hands and gently wiped away the tears, "You still have me" And he pulled Yugi in a hug, "I will always be your side, so don't cry"

"Forever...by my side?" Yugi asked once again innocently.

"Yes, forever by your side" Yami answered and Yugi grinned his face leaning closer to Yami whose heart was thumping madly.

"Then I want to sleep with you" Yami's eyes widen.

"I'm going to turn off the light"

"Okay" Yugi replied in a cute voice hopping in bed with Yami.

"Actually it's not too bad that he became a kid...next time I must feed him the imitation memory mushroom" Yami watched as Yugi cuddled closer to him on his bed. He stared at Yugi's sleeping face whose eyes were closed. "Yugi...why is it that you can't fly anymore..."

"...I can fly!"

"What?" Yami watched as Yugi opened his eyes.

"I know how to fly" Yugi stated and he slowly got up from the bed. Small white wings sprouted from his back and he laughed, "See..."

Yami just sat on the bed with a stunned and amazed look, "Yugi...?"
