Step 3: There is 2 sets of stone slabs that you must match up. Some in the Minecart area, and some at the bridge area. Now this only requires 2 people, so let your other guys distract the crawler. Heres my strategy on how to do it. One person steps on a slab and says what the symbol is , ex. Big circle little circle. Then that person steps off the stone, while the other person then steps on his/her stone, looking for the stone with Big circle little circle. When he/she finds it, they both step on the same one to match it. Then they disappear. Repeat this until there are none left. Then the british guy will talk about the focusing stone. A crystal ball will appear on top of the place he is stuck in.
Step 4 After the crystal ball appeared ontop of the place he is in, you have 3 people go to the bottom of the slide, have the 4th person activate the "Dont press X" button, then have him go to the bottom of the slide, so all of you activate the pressure pad. Then a crystal ball falls out of the sky.
Step 5 After the crystal ball falls out of the sky, you must then get the Shrink Ray and shoot it. It will shrink, and then you knife it into the water slide. It will the go on the geyser shoot. Shoot it up to the surface, and it will go on the ball holder. You should now have 3 crystal balls.
Step 6 Now we are stuck on this step. But we found out something interesting. When you shoot the shrink ray at the crystal balls, they will pass red streams to each other. And when you activate the right gong, the balls will light up red.
