What are you talking about? The story in this game is amazing. Donkey Kong's Island home island IS INVADED BY VIKINGS.
VIKINGS.
I don't understand. What more do you want? The story in this game is told through visuals and music. Story should NOT get in the way of gameplay. Ever. It is why many modern games that have a heavy narrative fail. This game succeeds however, because it tells a story in the levels. World 5 is a perfect example of this. We learn a lot about the fruit producing factory. What the factory makes, what the fruit looks like. The game doesn't tell us explicitly what's going on because that would be bad storytelling in the medium of video games.
Also, remember 5-2? That penguin on the machine? We really saw the desperation of the Vikings. They were absolutely DESTROYING the factory, and they didn't care. They are afraid of Donkey Kong, and don't want him to get back to his island, and will at any costs try and stop him.
This is how you do story in video games.
NO CUTSCENES.
NO DIALOGUE.
Through the visuals and sound in the actual gameplay.
