When a small platypus visits the zoo, the animals all assume he has come about the vacancy and he is swiftly taken through a rigorous interview process. But the platypus is far too bland for the chameleons, not nearly graceful enough for the flamingos, and his tricks will never impress the monkeys. So, he leaves. The animals soon regret being so unkind, but . . . what’s this? The platypus has left an invitation! Oh dear – it seems he had actually come to the zoo to invite them all to his party . . . But with all forgiven and forgotten, the platypus welcomes his new zoo friends to a fantastic party on his Platybus!
