Follow that Boat / Windmill Monkey

S5, E9: Follow that Boat: Steve needs an A to pass his history class and his model papyrus boat is sure to make the grade. George helps him test the boat in Endless Park's pond, but a sudden rainstorm sweeps it down the sewer grate! While searching for the boat, Steve and George learn that debris from the street ends up in the ocean. Will they ever find Steve's little boat in the big ocean or will he be taking history again next year? Windmill Monkey: George proudly finishes planting his rooftop garden when he turns around to find that Compass and his friends have eaten all the seeds. The scarecrow overlooking the garden didn't scare them at all! While buying more seeds, George spots a windmill and learns how the wind can power just about anything. The inspired monkey sets out to create the world’s first wind powered scarecrow in hopes that will keep his seeds safe. But some things are more easily planned than done!
