In a quiet town, a wave of gray has swept over a little school. Happy kids are now bored, bored, bored. Charming halls and playgrounds are now dull, dull, dull. Buzzing teachers are now tired, tired, tired. Something has to be done to bring color back to school.

Then one gray afternoon, a student gets a surprise gift that can help save the day: a box of seven special crayons! With the charm, determination, and cleverness of these peppy crayons, the students and teachers work together to make their school magnificent.
