Somewhere on the South Pole live the last four penguins of Katona. What makes these penguins special is that they only eat bananas. When the only banana tree in the South Pole falls down, the penguins go on a journey to find a place where bananas are abundant. That place turns out to be the banana stable of uncle Jaap, Albert Cuypmarkt, Amsterdam, the Netherlands. After a dangerous journey they arrive at the market stall of uncle Jaap. But what should uncle Jaap do with four penguins?
