Noggin really plays music! This fun collectible looks, and sounds, exactly like the lovable monster from the popular mobile game My Singing Monsters! The monster’s percussive perfection is worthy of a toe tap when it plays solo, and fits perfectly with other monsters in the collection when they sing and play together! The collection of monsters seems to come alive when they sing together because of the unique and impressive technology that allows each monster to “know its part” and jump into the song at just the right time! Collect multiple monsters, set them near one another, and they'll jump in and sing in sync! The more you have, the fuller your song! Noggin stands about 3" tall and comes with one of its favorite accessories—Traveler’s Sign! Button cell batteries included.
