Max's Grasshopper

s. 4, ép. 128: Max befriends a grasshopper while Ruby and Louise are trying to do a Bunny Scout experiment to measure how quickly their bean sprouts grow. But Max and Hoppy keep hopping in the way. When Hoppy starts eating the bean sprouts, the girls are devastated, until they realize that they can alter their experiment to measure how much higher a grasshopper can hop if it has more energy.
