TV series about imaginary 2D friend of a real boy.

Hi, there!

I watched it as a child, so it should be from 80s/90s. I think it was a TV series, but could have been a movie or a commercial too. I recall the real human was taking that 2D character(who was so small, it was fitting in his open hand) and putting him in his backpack to take him to school.
I am not sure, but I think it could be that the boy drew that 2D character and it unexpectedly became alive for some reason, like jumping out from the drawing.

I just recently learnt about Mandela Effect and I want to find all the series and movies that I can recall.
