7-B Feather Fiend
Donkey Kong and Diddy Kong have reached the end of the factory and have encountered Colonel Pluck, who is operating the Stompybot 3000. A Tiki decides to take control of Colonel Pluck and tries to smash you.
The Stompybot 3000 has only one vulnerability and it is not always accessible. For the first part of the battle, just stay out of the way. You can’t jump over the tall Stompybot 3000, so move under its feet as it walks.
When the bottom panel with the spikes rotates and reveals green chains, get in between the robot’s legs and jump up to grab on to the chains.
While holding on, pound on the chains to damage the Stompybot 3000. As the panel rotates again to reveal the spikes, move out of the way.
The Stompybot 3000 will try to roast you with its flame jet if you fail to inflict damage on it when it is vulnerable. So if you can’t get onto the green chains to pound it, quickly get away before the flames come at you.
Damage the Stompybot 3000 three times and you will break off its legs and end the first round. However, there is still one more round in this battle.
Colonel Pluck will now fly around trying to drop eggs on you. If they hit you, you will lose a heart. The eggs crack open to release BuckBots. Jump on their heads to clear the area.
While you are dealing with the BuckBots, Colonel Pluck will try to smash you. Jump out of the way and then jump on top of him to cause some damage.
Get in three hits on Colonel Pluck and he will be down for the count.
As the Tiki reappears, run up and hit it to finish the battle and unlock the next world as well.
