"Oh!" screamed Flossie, as she saw the big turtle so close to her. "Can he get out of the water, Daddy?"
"No, indeed," laughed Mr. Bobbsey.
"I can't see him very good," said Freddie, and he gave a little jump up from the foot-rail on which he was standing.
Freddie must have jumped up harder and farther than he had any idea of, for before Bert, who was standing near his little brother, could put out a hand to hold him, the flaxen-haired twin had fairly dived over the rail, and down into the tank he fell with a great splash.
No, not such a great splash, either, for Freddie did not fall directly into the water. Instead, only his two fat legs and feet went in, for the small boy landed, sitting right up on the broad back of the big turtle! Right down on the turtle's back fell Freddie Bobbsey!
CHAPTER XII
IN THE THEATRE
There was a scream from Nan, another from Flossie, and a sort of grunt of surprise from Bert, as they saw Freddie disappear over the railing of the tank, and come into view a second later on the back of the turtle, which was as much surprised as, probably, the little boy himself.
"Here, Freddie! What are you doing down there?" asked Mr. Bobbsey, before he thought what he was saying. He and his wife had so often to ask what Flossie or Freddie were doing, as the smaller twins were so often in mischief, that the father did it this time.
