Pupaphobia

Pupaphobia is the fear of puppets and marionettes. This phobia is slightly common, but not as common as coulrophobia (fear of clowns) and pediophobia (fear of dolls). Pupaphobia falls under the broader category of automatonophobia, the fear of anything that falsely represents a sentient being—this includes ventriloquist dummies, animatronic creatures, mannequin, and wax statues.
