The Puzzler is one of the five Meanies in Numberjacks. The Puzzler is a 3D-CGI-animated floating human head with glasses and orange bubbles that look like head hair and facial hair. He mostly speaks in rhyme.

The Puzzler pours little bubbles out of his mouth to cause problems. He also traps Numberjacks in big Puzzle Bubbles.

He gives missioning Numberjacks puzzling challenges, and when they've completed, they return everything to normal, but the Puzzler promises he'll be back before the Numberjacks return to the sofa.
