Apparently when the Wanapum Dam was built they never went to Bedrock. That is likely the reason for the crack that must now be repaired. The discovery of colorful Pebbles in the Rubbles led the wham-Bam-Bam-thank-you-ma'am decision to fix it as soon as possible. So, courtesy of Fred's two feet, at the Dam quarry Mr. Slate hired Joe Rockhead to lower Dino via a brontosauruses neck under water to repair with a wooly mammoth vacuum cleaner. The moment will be captured by a bird carving the picture on a stone tablet with its beak. Yabba dabba doo. Time for a 3 way with Wilma and Betty.
