Penelope K, by the way - Tongue

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. When investigating why some people can curl their tongues and others can't, Penelope K is shown different birds, different fish and different musical instruments. She's also shown a snowflake... and no two snowflakes are alike. All these facts lead her to understand that everyone is different. No two people are alike and that's why some can curl their tongues while others can't.
