Where do lock babies come from? THEY COME FROM THE CAVE. Stone "Tom Green" Lock uncovers an ancient baby mine where babies seeped deep into the earth to later be uncovered by baby excavations. However, little does Stone "Tom Green" Lock know that the cave was actually an ancient trap set by Explosive Lock. Explosive Lock is upset Stone "Tom Green" Lock knocked off the Cutlass Classic insignia from his car, so he is going to eat Stone "Tom Green" Lock. However, Stone "Tom Green" Lock is made out of lots of minerals, and you can only eat so much minerals in one sitting. So Explosive Lock gets a tummy ache. I hope I didn't give away too much of the plot line. Regardless, the most important thing to know is LOCK BABIES COME FROM THE CAVE.
