Penny Crayon is a 1989 British children's television series that tells the adventures of a very intellectual and well-meaning (but occasionally mischievous) schoolgirl from London who loves to draw, and her escapades accompanied by her best friend, Dennis.

Using the magic crayons that she always carries with her, she brings everything that she ever draws to life, to either help them on their adventures or to get them out of tricky situations, and usually creating a world of chaos until it is either erased or washed away.

It was made by Maddocks Animation, which had previously produced Jimbo and the Jet-Set and The Family-Ness, and utilized much of the same production staff, as well as featuring the vocal talents of Peter Hawkins in all three series.

Penny Crayon was originally created by Maddocks as a gag comic in the girls' magazine Jinty in 1976.

When she and Dennis can't catch them to erase them, she eventually draws a huge cage to put them all in, thus allowing her to rub them out.
