There was some silence for some time, until the Caterpillar stared at Yusei with his tired eyes.
"Who are YOU?" he asked.
"I don't know," said Yusei. "I've changed so many times since this morning, and-"
"Explain yourself!" said the Caterpillar. "I don't understand."
"I can't explain myself," said Yusei. "I'm not myself, you see, because-"
"I don't see," the caterpillar interrupted.
"Well, I can't put it any more clearly, because it isn't clear to me!" said Yusei. The Caterpillar stared at Yusei again.
"WHO are you?" he asked again. Yusei sighed. "Everything today is so confusing…" he sighed.
"It isn't," said the Caterpillar. Yusei frowned at the Rex look-a-like. "It is to me, because I can't keep the same size around 10 minutes all together!"
"Why?" the Caterpillar asked. Yusei frowned at the Caterpillar again. Before he felt as if he was about to loose his temper, he turned away and walked off. "Hey! Wait! Come back! I have something important to say!" said the Caterpillar. Curious, Yusei turned back and faced the Caterpillar again, who was continuing to smoke his hookah. "Keep you temper," it said.
"IS THAT ALL?" Yusei shouted, feeling as if he was about to irrupt any moment.
"No," said the Caterpillar, turning to face Yusei again. The was another silence for a few moments, until the Caterpillar spoke: "Why do you think you've changed?"
"I told you," said Yusei. "I can't keep the same size, and I can't seem to remember anything that I USED to know."
"Do you know any poems?" asked the Caterpillar.
"No, I don't," said Yusei. "Poems aren't really my thing."
"What about the little busy bee?" asked the Caterpillar. Yusei thought for a moment. "Vaguely."
"Go on!" ordered the Caterpillar. "Recite!" Yusei sighed and spoke:

"How doth the little Crocodile,
Improve his shining tail,
And pour the waters of the Nile,
Of every golden scale?
How cheerfully he seems to grin,
How neatly spreads his claws,
And welcomes little fishes in,
With gently smiling jaws!"

"Young man, that was wrong from beginning to end!" said the Caterpillar.
"Well I don't remember!" Yusei shouted. "I'm a kid any more, you know!"
"I don't know," said the Caterpillar.
"Quit saying your short sentences!" said Yusei.
"Quit losing your temper!" said the Caterpillar. There was another silence for some while. Yusei waited until the Caterpillar was first to speak again: "What size do you want to be?"
"It doesn't REALLY matter about size," said Yusei. "I just want to be a little larger, that's all."
"Why?"
"Because 3 inches is such a wretched height, and-"
"I AM EXACTLY THREE INCHES HIGH!" the Caterpillar cried. "AND IT IS A VERY GOOD HEIGHT INDEED!" It sat down and smoked its hookah angrily.
"But I'm not used to it!" Yusei pleaded. There was another silence for another few moments until the Caterpillar began to crawl away. "One side will make you taller, and the other side will make you shorter," it said.
"One side of what?" Yusei asked himself.
"Of the Mushroom," said the Caterpillar, and disappeared in the grass. Yusei sighed.
"That's no good," he said. "A circle doesn't have any sides. But I don't care right now!" Impatiently, he grabbed each side of the mushroom and looked at them. After thinking about it for a while, he took a nibble of the right side. Suddenly, he felt is neck stretch, his body felt longer; he could feel his body expanding as he got larger.
'Uh-oh!' he thought, as he headed for the trees. Then, his head reached above the trees and he stopped growing. "This is going to take a while," he said to himself, as he nibbled the right side of the mushroom. Then slowly, he worked his way down to a perfect height, and found himself lost in another forest.
