Tutter (born Tutter T. Tutter) is a blue mouse who lives in the Big Blue House with Bear on Bear in the Big Blue House. Tutter now lives in his mousehole, but for a time, he was raised by his Grandma Flutter, according to "The Big Little Visitor." Bear has baby pictures of him, so it's not known exactly when he moved into the Big Blue House. Tutter knows a lot about cheese and enjoys eating it, talking about it and reading about it. Because of his small size, Tutter sometimes needs Bear to help him reach high places. This sometimes upsets Tutter, but he normally accepts this help with an endearing "Thank you, Bear." Tutter has a large family. Besides his Grandma Flutter, who has taught him many things, he also has cousins, aunts and uncles (although his parents have never been seen nor mentioned). Many of his relatives are seen in "The Tutter Family Reunion." In the fourth season of the program, Tutter began attending Mouse School, taught by Miss Maxwell. When Tutter is annoyed or upset about something, he will sometimes start shouting names of cheeses as if they were epithets. Another favorite saying of Tutter's is "Oh, hickory dickory!" (after the mouse who went up the clock.) One reason Tutter gets so upset is that he tends to focus a lot on cleaning and doing chores (a la Boober Fraggle). He likes to do these things perfectly and gets upset sometimes when they don't seem to be working out. Tutter also has a tendency to worry and fret, another similarity to Boober Fraggle. He sometimes keeps his problems to himself, but generally finds that talking to his friends, or Bear, helps. Another characteristic of Tutter is that he has big dreams and thinks big about himself, but often finds himself at a loss when asked to describe what's unique or special about him. Tutter is sometimes seen sleeping with a stuffed kitty. In the show's pilot, Tutter was initially conceived as a girl named Mouse. Joey Mazzarino was also considered for the role at one point.[1]
