Molly and Prutt, two monster friends, visit a preschool where the children ask for help finding a treasure in the nearby forest, as they are afraid to go themselves. The monsters find an owl in the forest who gives them a map. Following clues on the map, Molly and Prutt dig at a marked spot and discover a locked treasure box. They must then follow additional maps to find the key under a bridge. With the key, they unlock the box to find gold, silver, and diamonds inside. The monsters return triumphantly to the preschool with the heavy treasure box for the children.
