Kongo Bongo Gone Wrongo

Kongo Bongo Gone Wrongo is the mysterious, contagious, and fatal disease that Diddy Kong catches after being bitten by its carrier, Polly Roger, the treacherous Tropical Toucan. It is only seen once in the 29th episode of the Donkey Kong Country animated TV series, Speak No Evil Dude.

Its only known cure is the nectar of the rare Tin-Banana-Tu banana, which is a purple species of banana with an extremely foul taste, according to King K. Rool. After Diddy Kong tricks Cranky Kong by using two coconuts, Polly Roger infects Diddy by pecking his rump. Afterwards, Diddy spreads the disease to Krusha, who then spreads it to King K. Rool, simply because he cannot stop sneezing as a result of the disease, even though General Klump orders him to be silent.

Symptoms
The deadly symptoms of the Kongo Bongo Gone Wrongo disease are explained through song by Cranky Kong, Candy Kong, and Dixie Kong:

Cranky: First, you get the chills from your head to your toes.

Then, your nose starts to run til it overflows,

Next, you're sneezing so hard, you'll throw out your back... and then WHAM, Laryngitis stops you dead in your tracks!!.

Candy: When you're shaking so hard, and chilled to the bone.

You're colder than a yeti or banana ice cone,

Dixie: You shiver and you quiver, you grow weak and feel old,

Freezing cold & wheezing, you look greener than mold,

Cranky:'' The only cure... is nectar of Tin-Banana-Tu.''

Candy: It's like having the flu, times one hundred and two,

Dixie: You'll wind up in bed, but you'll wish you were dead.

Cranky: A disease that goes right to your HEAD!!

Candy: Your voice goes all raspy until you can't talk,

You can't talk and it feels like you swallowed a sock.

Dixie: Soon you'll hear the sound of your brain cells go POP.

Until there's nothing left, Oh no, please make it STOP.

Cranky:'' The only cure... is nectar from Tin-Banana-Tu.''
