Flupperius Petallus Pongus
From the Super Mario Wiki, the Mario encyclopedia
The Flupperius Petallus Pongus is a red flower that appears in Donkey Kong Country 3: Dixie Kong's Double Trouble!. It is needed to complete a trade that earns Dixie and Kiddy Kong a Banana Bird.
Bramble is seeking a Flupperius Petallus Pongus that he can study, but none are able to grow due to the pollution caused by the nearby factories on Mekanos. When the Kongs revisit Bramble after defeating KAOS in Mekanos, Bramble reports that the plant life can continue growing, although the Flupperius Petallus Pongus is yet to bloom. Once the Kongs complete Razor Ridge, the flower blooms at a dead-end path right next to Bramble's Bungalow.
In the Game Boy Advance remake, the Flupperius Petallus Pongus has a slightly different purpose and is acquired differently. When the Kongs first visit Bachelor, he gives the Flupperius Petallus Pongus to them. Dixie and Kiddy can then go to Bramble's Bungalow and trade the flower for a Rose, which they must give to Bachelor for a Banana Bird.
