MDK2 Easter Egg - Giant Conehead

First, reach level 7. One part of the level is a room called "Spider Room," it is the one with the 8 columns that you must activate one by one to activate a teleporter. When you are there, go until swarm 6 (I think), it's one in which you are surrounded by Coneheads. When you snipe the ball, DO NOT MOVE. Just stare to the center of the room; the coneheads won't attack you. After around 1-3 minutes of staring, you will see a giant conehead. It will show the head and dissapear. It's not interactive; if you walk to it it vanishes. When it disappears, the coneheads will start to attack.
