No matter how much the pink monster grunted, the door still wouldn’t open.

“Let me do it,” said Rocky.

“No… I can do it just fine,” said the pink monster.

So Rocky stood back with his paws crossed till a half hour later, when the pink monster finally gave up in a lake o’ sweat.

“All right…” the pink monster panted. “If you’re so smart… You do it, then.”

Rocky nodded & then stepped up to the door & pulled it open as if ’twere a piece o’ cardboard.

The pink monster jumped. “¿How’d you do that?”

“The door only opens for those with ‘nough thieving experience,” said Rocky.
