The Stranger Arrives (II) - S1.E2

The only contact with Poopsnagle that remained was a telephone number. When Garcia called the number, he got a message machine. He left a message for his old friend to contact him at the Secret Valley holiday camp. Instead of Poopsnagle, Garcia was surprised when a young boy of 12 years old turned up instead. It was none other than Poopsnagle's grandson. Together they resolved to build a flying bus which was originally designed by Professor Poopsnagle to help them in their search for the minerals.
