Cranky is giving vaccinations for the ""Kongo Bongo Gone Wrongo"" disease. Diddy, not wanting a needle, tricks Cranky but then Diddy gets the disease and in the process spreads it to Krusha, who in-turn spreads it to K. Rool.

While fishing with Diddy, Donkey Kong finds a bottle with a message in it. It's a note from the ""Federation of Future Rulers"" and it seems Donkey Kong may have to leave the island. So the others have a party for him, remembering some of the times they had together.

Funky makes like a seer, using a lava lamp he has to make predictions, and surprisingly the predictions actually come true!

Candy wants Donkey Kong to marry her. Donkey Kong feels awkward about the whole thing (as he doesn't want to get married, but doesn't want to upset Candy either).

Bluster, unhappy with Donkey Kong being the future ruler of Kongo Bongo, tells Cranky he wants an election held to decide who should be future ruler. Upon overhearing about it Klump tells K. Rool, who then also enters the election.

Donkey Kong and Diddy are practicing for a soccer game. In the process, Klump and Krusha end up with the coconut DK & Diddy are using, thinking it's the Crystal Coconut they take it to K. Rool. Then both DK & Diddy and Klump & Krusha keep switching the coconuts (while trying to get the Crystal Coconut).

While Cranky goes to Bluster's, Donkey Kong is left to guard the Crystal Coconut. Donkey Kong fools around with an invention of Cranky's, a mind transfering device, accidentally switching his mind with a robot Cranky had built. Klump and Krusha steal the mind transfering device. While heading back to K. Rool, Klump bumps into Candy and they get their minds switched.

Bluster, while trying to get Candy again, finds his hair is falling out. He mixes a bunch of hair tonics, and the resulting brew ends up turning him into a suave, smooth talking ape (who goes by the name Leo Luster).

Donkey Kong and Diddy find out Cranky and K. Rool used to be friends. So they plan to get them back together, and seem to succeed, but K. Rool is just acting the part (to show-up Cranky in a competition).

After some mishaps (that get everyone angry at him), Donkey Kong feels Kongo Bongo would be better without him. As he's about to leave he hits a tree branch, getting knocked out, and has a dream of what Kongo Bongo might be like without him.

It's ""All Fools Day"" on Kong Bongo, and Cranky is playing pranks on Donkey Kong, Diddy and Candy. So they conspire to pull a big trick on him.
