Mary Jane

Personailty
As Henry Huggins says, Mary Jane is a sensible girl who cannot have sweets (Like Susan) but has tried bubble gum before. Mary Jane is also a fast learner, as proved in Henry and Beezus when she quickly learned to blow bubbles without Henry's help.

Trivia

 * Henry calls her  a sissy, and she is the reason Henry says "Beezus is pretty sensible for a girl".
 * Ramona claims in Ramona the Pest that Mary Jane loves to babysit children, and even forces her into playing.
