Life has never been dull for Billy and his dog Buddy, but ever since the circus arrived in the neighborhood, it’s been getting better and better. There are crocodiles, ostriches, penguins, elephants... There’s little Vittorio and his pet chameleon... And of course, Caroline the tortoise and Buddy’s dog friends are still here. Oh, yes, quite the merry gang all right – and one who occasionally drives Billy’s parents mad!
