"When an Airy Frogfather grants Flamingo's wish for a fancy new home for his inflata-pals, he's pumped! But to claim the palace, the gang will have to go up against Sir-Spits-A-Lot, an evil inflatable llama who won't give up the castle easily. Will Flamingo have what it takes to survive llamagedon and become the rightful air to the throne?"--
