Mini-Doris is the secondary antagonist of Meet the Robinsons.
Meet the Robinsons
Mini-Doris is a small remote controlled helping hat created by DOR-15 to assist the Bowler Hat Guy in traveling through the house while she stayed in the time machine. She has the ability to control creatures mind when it is put on. She took control of Frankie and Tiny the Tyrannosaurus. She is defeated when Wilbur shoots her off Tiny's head with Gaston's Meatball Cannon. Frankie and the other frogs then grab her and throw her, scared, into the trunk of a car. Afterwards, the Bowler Hat Guy comments that she now "sleeps with the fishes," indicating that she was destroyed by the frogs. In any case, she was erased from existence when Lewis erased DOR-15.
