Mr. Ellis, the museum curator, is planning a Time Capsule, to which everyone in town contributes an item. Bob builds a metal chest to be used as the Capsule and he and Wendy are to dig a hole outside the museum to bury it in. While they are inside the museum, Spud comes along and finds the Capsule. Thinking it is some sort of treasure chest, he loads it into the back of Travis's trailer, throwing out all the items inside en route, since he thinks they are complete rubbish. He collects his own 'treasure' (feathers, bits of twig etc.) and puts these in instead. However Farmer Pickles' dog, Scruffty, has seen Spud take the Capsule, and leads Bob, Farmer Pickles and Mr. Ellis on a trail. They find Spud just about to bury the Capsule, and take it back to the Museum for its proper burial. Spud is reprimanded, and Scruffty is declared a hero for saving the day.
