Sherlock ran after the criminal. "Come on John!" he cried. John caught up with him.
Now, as you know, Sherlock observes everything.
What he didn't observe was the hole beneath him.
Soon, he was falling. Like the time when he fell from the building. But this was different. He just couldn't put his finger on it.
John fell. He shouted out and caught up with Sherlock. "WHAT'S HAPPENING?" He cried.
"I don't know!" Sherlock said. He grabbed John's hand and they hit the ground.
Sherlock looked around. "Where are we?"
"I don't know," John muttered. He looked around. Strange mushrooms grew, and plants wove their way into the place. John saw a bottle.
"'Drink me'? What is this, Wonderland?" John muttered.
"It is."
"WHAT?!" John turned to Sherlock.
"It is. The liquid inside that bottle makes you smaller, which you need to do in order to get out of here." Sherlock nodded to the tiny door.
John sighed and drank the liquid. He shrunk. Sherlock drank liquid too and shrunk.
"I'm still taller than you," Sherlock grinned.
"...Shut up Sherlock."
