In the book version
Tutterly T. Tutter is Tutter's great-grandfather. A famed explorer, Tutterly collected cheese from around the world, and buried his pile. He appears in flashbacks in the Bear in the Big Blue House episode "Raiders of the Lost Cheese" and the storybook adaptation.
Tutter and Ojo find a map with the initials T.T.T. Tutter realizes that the map indicates the location of his great-grandfather's long-lost cheese trove. By the time Tutterly's descendent finds his treasure, the cheese in the chest is rendered moldy and inedible. However, he has left behind his trusty compass, proving to be a more valuable treasure.
