Combo Delights! The only toys to combine the ruggedness of our Ruff-Tex with the extra-plush corduroy of our 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 our Ruff-Tex Balls and our Knotties, making Huggle-Fusion the best of both worlds! (One size only!)
