Walkthrough: From your starting point, head left to see the Bonus Barrel in the air. There's a Gnawty if you head right who could assist you to get into the barrel by bouncing on him using Diddy.
This room has four barrels with interchanging items inside them. You have to spell the word "KONG" to get the 1 Up reward by waiting for K to appear on the first barrel, O on the second, N on the third, and G on the last. Hit when the letter appears on the right barrel, otherwise, the game will end in failure. Hitting the banana icon also instantly ends the game.
