Blue Monster Tooth Fairy PillowMeet Blue the Tooth Fairy Pillow. Blue's mouth is perfect for holding teeth, money, prizes, and surprises! Blue is an 8 tooth pillow flat enough to fit under a pillow but huggable enough to sleep with every night. Arms, legs, ears, and tails make Blue easy to find and grab. All our tooth pillows have a lost tooth tag (called a Substi tooth!) for those times that a tooth goes missing (or falls down a sink)!
