The Renkins' are having a problem with their grape yard. A group of gophers have made their home in the ground under the garden & are stealing the grapes. Upset with the problem, Mr. Renkins calls Calhoun the Gopher-getter, an exterminator, to come & catch the gophers. George doesn't like the idea of somebody catching the innocent gophers, even if he does plan to release them again. So he decides to build a connecting tunnel between his house & the Renkins' garden so the gophers can escape.
