Tortoro is on the right. (I think.) Totoro is a giant, friendly forest spirit. He spends most of his time sleeping in a hole in a tree. He doesn’t speak, instead communicating by loud bellows that, it seems, only the other Totoros and the Cat Bus can understand. He is very friendly to Mei and Satsuki. He can make trees grow much faster than normal.
My Neighbor Totoro is a 1988 Japanese animated fantasy film which tells the story of the two young daughters (Satsuki and Mei) of a professor and their interactions with friendly wood spirits in postwar rural Japan. The film won the Animage Anime Grand Prix prize and the Mainichi Film Award for Best Film in 1988.
