Instructions
Go to spiral hill and head up to the windmill. Go down the spiral path into the windmill and walk through the door. This will take you to Poo Land. Go up the steps and talk to the Weasel Mob Boss. You'll be given a costume reminiscent of "The Matrix" and briefed on your mission.
Go up the steps again and go through the revolving doors. After the cut scene, dash behind the pillar to your right. Press "B" when you hear the weasels' voices to perform a slow-motion jump.
Move the cursor over the enemies while you're in mid-air. They will die and you will land behind a pillar on the left hand side. Repeat this process for each wave of weasels until you reach an elevator. Go inside and you'll be taken to the second floor. Wait for Berri, Conker's girlfriend, to turn the lasers off for you.
Head into the vault. Use the frying pan to hit the money running around. Pick up three of them and a cut scene will begin before you fight an alien.
Turn to your left and push the switch. This will open an air lock and a door at the other side of the room. Put on the space suit you'll find inside the door.
Run up to the alien and repeatedly press "B" until the alien lays on the ground, unconscious. Run around to his tail. Turn the analogue stick slowly, counterclockwise, to swing the alien around.
Press "B" to toss the alien into the airlock. He will cling on by his fingers, and you will have to repeat the process twice more to defeat him.
