Of course you enter the dark, dank, questionable cavern. What programmer would not?
OH NO! Out hops a monster!
"Grr," says the monster. But other than that, appears friendly enough.
The monster holds out a treasure chest, and speaks:
"You can have the 5 gold coins inside my treaure chest if you enter cavern 4 and come back out alive!"
"What!" you exclaim. "I'm already in a cavern. How can I enter another one!?"
"Why not try it?" says the monster.
Do you enter cavern 4?
