"Oh!" cried Sue, as she saw this. "I wouldn't like him to bite me, would you, Bunny?"
"No, I guess not!" said the little boy.
But there was no danger that the hippopotamus would bite anyone, for he was behind big, strong, iron bars, and could not get out. There was also a baby hippopotamus, swimming around in a tank with the mother.
Bunny and Sue saw many other animals in Central Park, and then, as he was getting hungry, and as he began to think his mother might be wondering where he was, Bunny said to Sue that they had better go back home.
"All right," Sue answered. "I'm tired, too."
They went back to where they had left the automobile taxicab.
"Well, did you see enough?" the man asked them.
"Yes," Bunny answered, "and now we want to go home, if you please."
"All right," said the man. He knew just where to take Bunny and Sue, for he remembered where he had found them, right in front of Aunt Lu's house. So the two children did not get lost this time, though they had gone a good way from home.
"Thank you very much," said Bunny as he and Sue got out.
