Some children may find the Birthday Girl scary.
None in a lot of episodes.
For preschoolers/kids and up.
None/Moderate for neurodivergent viewers.
In one episode, Wordgirl bends a steel brace to threaten the villains out of frustration. This may be irreverent to some people.
If wordgirl was a movie rated pg for mild action/peril and thematic elements.
Miss Power can be very frightening.
Dr. Two-Brains may be frightening to children, especially in the episode "Mouse Brain Take-Over"
Nothing more than a typical 3-4 year old could handle.
