The Little Yellow Digger at the Zoo by Betty & Alan Gilderdale

"Too many hippos," the chief keeper said as he took off his cap and he scratched his bald head. "I'm afraid that a number may soon have to go." But the keeper's assistant quite loudly said, "No!"

The little yellow digger comes to the rescue again!

Betty and Alan Gilderdale join forces once again to bring you the next adventure from one of New Zealand's most-loved children's books, The Little Yellow Digger.
