It’s the last of the autumn days before winter sets in, which means it’s time for CARNIVAL! And Hotel Flamingo, the sunniest hotel in town, is all set to join the party. Animal Boulevard is a riot of colour, and every establishment is preparing a float for the annual procession. Anna is determined to win the prize for Hotel Flamingo for the best display, despite rival hotel the Glitz having won it every year since the Carnival began. Meanwhile Hotel Flamingo is welcoming its usual array of eclectic guests. Wilbur the sheepdog, who has no home, and needs a place to stay and someone to give him a chance at a new start. Mr and Mrs Kunkworth, a pair of skunks, who are rather anxious, and Mac Macaw the parrot, who is quite the opposite. Things start to get complicated, though, when Anna gets some very unexpected guests – the mega-famous band The Nocturnal Animals!
