Combo Delights! The only toys to combine the ruggedness of the Ruff-Tex® with the extra-plush corduroy of these Knotties®, Dude the Turtle, Bugsy and McCracken Lobsta boast "pass-through" knotted limbs - arms and legs that extend through the toy's body for maximum tugging and strength. They deliver all the perks of the Ruff-Tex Balls and these Knotties, making Huggle-Fusion™ the best of both worlds! (One size only!)
