Louise went to the edge of the pool and peered down into the water.

“I don’t see anything.”

“You will in just a minute. Keep looking.”

Louise was more than half convinced that Penny meant to play some prank, but she dropped down on her knees so her eyes would be closer to the water.

“Why, I do see some large object on the floor of the tank!” she exclaimed after a moment. “What is it, Penny?”

“An alligator.”

Louise gave a smothered scream and drew back from the pool’s edge.

“I—I might have fallen in. You ought to be ashamed of yourself!”

“I only wanted you to get a nice thrill,” Penny grinned. “Pretty fellow, isn’t he?”

“I didn’t really see him,” Louise admitted.
