Elmo, Abby, Rudy, and Chris want to make their own pretend plane so Rudy can see what it’s like to fly in one. The airplane is almost finished, but they’re missing the propeller and they ran out of cardboard. This is a problem! The friends try a couple of ideas and then wonder what else they can use. What if they make a propeller from a spinning pinwheel in Abby’s garden? It works! They didn’t give up and now their plane is ready for take-off.
