Aggressively growing plant life starts to overtake various parts of the world, so Jerry pulls the girls away from Spring Break to have them check it out. And as they do, the spies immediately find themselves having to battle the plants which seem to have turned on them. Ultimately, they discover that the plants are starting to take over the world and someone is behind the scheme -- and that someone is Shelly Junglelove. Her goal? To overrun the world with her special, aggressive, fast-growing planets so that she can turn the earth back to simpler times. It's up to the spies to weed-whack Shelly and save the planet. In a b-story, the spies spend Spring Break on the beach, where Clover tries out to become a Super Sunny Tropics sunscreen spokes-model.
