Penelope K, by the way - Worm

Penelope K runs the Information Station, a place which contains all the answers to any question a child might have. To help her find the answers, Penelope is joined by her sock puppet, Squirm; Hank and Frank, two wise cracking fish; Trewey, the shadow rabbit, and music is provided by the Rubber Band. Penelope K investigates if worms have eyes. Her journey takes her down a rabbit hole, into a dark tunnel and back out again, a bit like a worm wriggling out of its worm hole at night. All of this leads her to understand that worms don't have eyes because you don't need them if you live underground, but that worms can sense light rather like we can feel light even with our eyes closed.
