Lost in Time: Oz - Toto SP
Toto belongs to Dorothy Gale, the heroine of the first and many subsequent books. In the first book, he never spoke, although other animals, native to Oz, did. In subsequent books, other animals gained the ability to speak upon reaching Oz or similar lands, but he remained speechless. In Tik-Tok of Oz, continuity is restored: he reveals that he is able to talk, just like other animals in the Land of Oz, and simply chooses not to.
