The civilians of the Crayon Kingdom have always viewed their Princess Silver as a twelve-year-old girl with a beautiful smile.

The princess is so busy trying to find a suitable dance partner that she forgets to hide her bad habits.

They eventually find out that in order to destroy the Grim Reaper, Princess Silver must get rid of her 12 bad habits.

They eventually succeed, by reassembling the broken pieces of a mirror and deciphering the hidden code.

They finally realize that they have to "tickle the Grim Reaper under the left arm" to destroy him and send him back into the mirror.
