Clinky T. Clown is not just any ordinary boy; he's a Realclown with a mystery to solve. Clinky and his family live in the town of Happyville, which is populated with mostly Realclown citizens, or people who are born with a clown face.
On the last day of second grade, Clinky discovers that his great, great, great grandfather, the founder of Happyville, left a series of clues that must be solved in order to save the town.
Aided by his three best friends, Wacky Wizard, Glenda Goodness and Danny Dinglebat, Clinky is off on the adventure of a lifetime. Along the way, he also gets a little help from his second grade teacher, Mrs. Petunia Sourapple. It's a one hundred year old mystery that only Clinky and his friends can solve.
