"Doesn't seem to want to get its feet wet," Jack suggested.
"But it swam out to the boat the other night," Bob reminded him.
"Maybe it's got a boat somewhere."
"I hope not."
"Look out, he's going to throw another stone," Jack cried a moment later.
This time, however, the creature's aim was not so good and the rock, about the size of a baseball, struck the water some ten feet beyond them.
"Guess that first shot was an accident," Jack said but he changed his mind a moment later when he had to dodge sharply to avoid a third rock which was nearly as large as the first.
For some time the creature stood there on the shore throwing rocks at them and several times they narrowly avoided being struck.
"I say, this is getting a bit tiresome," Jack declared after he had barely escaped a rock nearly as large as his head. "I wonder if he's going to keep it up all the rest of the day."
"It's his move," Bob said grimly.
