Higher beak!

Bored under the African sun and sipping pineapple juice, two flamingo brothers - Flig and Fogo - unexpectedly receive a letter from the Cold Forest. In it, the bullfinch Bibus invites his brothers to his birthday. Fogo wants to throw the letter away since it was delivered to them by mistake, while Flig worries that Bibus will be all alone on his holiday.
