The sudden appearance of a tree on planet Gruble forces the Grubs to keep their promise to try growing up. Back on Earth, the "greatest show on Earth" is taking shape but Bill isn't impressed by Jason's dance number with Jane and Ralph. Darren uses the Woop to send Ebony a note attached to a rose asking if her clock was fixed. He anxiously awaits a reply that doesn't arrive — but Ebony does. Sitting on the porch she explains how Darren helping her fix the clock was the key to stopping the Grubs. Restarting it was what caused plant growth to restart on planet Gruble and was what allowed her friends to grow up. Her friends the Grubs.
