Thomas resides in the basement of the Middle House the center of Symmetry Village in the past. He seems to be very self-conscious about his slight build and has somewhat of an obsession with "getting the girls."
Thomas wishes to gain weight by working out. However, since he only has enough training equipment for one side, and training one arm at a time goes against his policy, he will be unable to do so. Link can give him the Dumbbell received from Mamamu Yan as part of the Trading Quest, allowing Thomas to exercise both his arms while keeping the town symmetrical. In return, he gives Link the Cheesy Mustache.
- Thomas was referred to as the Thin Man in The Legend of Zelda: Oracle of Seasons and Oracle of Ages — The Official Nintendo Player's Guide by Nintendo of America Inc. and the Unbalanced Man in the Oracle of Ages book by Craig Wessel. However, as these contradict the name given in Encyclopedia, they are not considered Canon.
