(EDIT - Old Kids LIVE action/cartoon)
Ok. will give a bag of gold to those who can help.
It's was a live action kids show that involved a kid who could draw, and one day upon drawing a small character (The kid might of had blonde hair, the character might of worn a cap) the character came to life and walked around his room talking.
Another factor was you never saw the parents face. Chances are it was early-mid 90's, maybe on BBC.
Thanks ahead :D
