Nick is trying to hang onto the monkey bars but can't. The Cat takes him and Sally to meet the best holder-on-ever, 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!
