Penelope K, by the way is a British–Australian television program for pre-school children. The program is produced by Blink Films and Freehand for CBeebies, the BBC's children's television channel.

In each episode, Penelope K is asked a general knowledge question by a child, which she answers by researching the contents and talking to characters inhabiting her Information Station.

Searching for answers she talks to her sock puppet called Squirm, a pair of fish named Hank and Frank and a shadow rabbit Tewey, while a band of musical instruments helps her find the answers through music.
