SEGAs Sonic the Hedgehog burst on the scene in the early 90s and is still running strong, with a fan base that spans generations. Knuckles has been both friend and foe to the speedy blue hedgehog, but rest assured hes 100% friendly (and so huggable) as a HugMe Shake Action Plush. The 16-inch tall plush comes complete with Kidrobots signature squeeze-sensitive vibration feature. Shake action when you hug it! Shake action when you clap! Batteries included.
