S1·E28 Hold on Tight

Nick is trying to hang onto the monkey bars but can't. The Cat takes him and Sally to meet the best gripper, his tiny little friend Larry, the limpet. After shrinking down to limpet size, Nick and Sally learn how to hang onto the rocks with the help of natural hand and footholds, some sticky stuff on their feet and plain old perseverance. Now Nick knows that in order to stay on the monkey bars, he needs to keep trying.
