The Incriptor Chip has fallen into a pyramid in the desert and Dr. Marbles was getting it, until he was imprisoned. The kids were called upon by Motherboard to go in and get Marbles and the chip. Unfortonatly, they have to get out before the gate of the pyramid has closed, locking them in for eternity. The gate drops down as the water drips from two cylinders. The kids find out there are 15 rings of water left and each ring drops out each minute, meaning they have about 15 minutes to go in and out. Matt's watch is broken and Jackie might sneeze again and lose count of time. However, they find an artifact moving at the same pace as the water cylinder, and then use a bunch of rubies and an even distributor to know how many seconds have passed and a ring and stick to know how many minutes they have left.
