Stinky the Stinkweed gets a new book called the "Great Big Book of Every Plant that Ever Was" by Dr. Lily Rosenbloom. Stinky tries to find himself in the book but he can't. Now Stinky's worried that he's not a plant at all. He's not a dog because he can't chase sticks. He's not a bird because he can't fly. Maybe Dr. Rosenbloom just made a mistake by leaving stinkweeds out of her book. The only way to find out is for Dr. Rosenbloom to visit Sesame Street and run some tests to determine if Stinky is, in fact, a plant. The Doctor arrives to investigate and observe Stinky. Will Stinky pass the plant test and get put in Dr. Rosenbloom's book? Tune in to find out! Brought to you By: L & 20 Educational Goal: Science Word on the street: Absorb To take in or soak up.
