Mercy Watson

Mercy the pig's love of buttered toast leads to the capture of a small thief who would rather be a cowboy.

Mr. and Mrs. Watson think it is a wonderful idea to bring their pet pig Mercy to the drive-in, and when Mercy arrives, she sets off on a mission to find her own buttery bucket of popcorn, much to the dismay of the other movie patrons.

Mr. Watson's usual Saturday drive in his Cadillac with his favorite pig, Mercy, turns into an adventure when an unexpected passenger shows up in the back seat and Mercy finds herself behind the wheel.

After Mercy the pig spends the night in the Watson's bed, all three awaken with the bed teetering on the edge of a big hole in the floor and it is up to Mercy to save them.
