Eight-year-old Mandy isn't what you'd call an emotional child.
Whether at her own surprise birthday party, scoring the winning goal, or being
stung by a bee, Mandy doesn't show her feelings. Instead she draws them as
MONSTERS in her sketchbook! But one day her emotions run wild and those monsters
escape! Mandy's only help catching them is an eccentric monster named
Happster, who causes more problems than he solves. Can Mandy catch all the
sketch monsters and return them to her sketchbook before they destroy her
town?
