Donkey Kong and Diddy Kong encounter some Mole Miners filling a mine train with bananas as they reach the end of the Cave world.
A Tiki sees the two apes and possesses Mole Miner Max driving the train. You need to get onto the train to stop them from taking away the bananas.
At the start, be sure to throw the DK Barrel since Diddy Kong will really come in handy during this level. For the first part of this boss battle, you are standing on a mine cart that is following the train. A Mole Miner throws pickaxes at you. Jump over the ones thrown low while ducking under those that come in high.
As your cart catches up with the train, you now have to attack the Mole Miners hidden in the bananas. When you see bananas in a cart moving about, get away from it. A Mole Miner will pop up and try to stab you with their claws. As soon as the Mole Miner puts its hands down, jump onto it.
After hitting several Mole Miners, you will see some of the wheels start to get blue sparks around them. Jump onto the cart whose wheels do not have sparks so you don’t fall when those four carts go off the track.
Your cart catches up to the train again. Dodge the pickaxes the Mole Miner throws at you. In addition, the Mole Miner will throw bombs at you. As they land on your cart, watch for them to start blinking when they are about to explode and jump up to avoid the blast.
When you reach the row of carts, jump on the Mole Miners as they lower their hands and then make sure you are on the cart that is not going off the tracks. You then have to repeat the cycle for a third time—dodging bombs and pickaxes and then jumping on Mole Miners. Use the same tactics as before.
Now you have to fight off Mole Miner Max. He will pop up out of the bananas and throw a pickax at you. Jump over it and land on his head. Hit him several times to knock him out and then run up and hit the Tiki to complete the level.
