Impressively, Riddell's illustrations can even be seen on special editions of Peter Pan, Treasure Island and JK Rowling's The Tales of Beedle The Bard.
Why has Chris Riddell accused John Lewis of plagiarism?
Chris Riddell claims there are similarities between his 1986 book Mr Underbed and John Lewis' Moz the Monster ad.
He wrote on Twitter: "John Lewis helps themselves to my picture book."
Despite this, the retail giant has hit back claiming the story is "utterly different".
The author told "The idea of a monster under the bed is by no means new but the ad does seem to bear a close resemblance to my creation – a big blue unthreatening monster who rocks the bed and snores loudly.
"Needless to say, I think Mr Underbed is a lot more appealing than Moz, but of course, I’m biased."
A John Lewis spokesperson said: "The story of a big hairy monster under the bed which keeps a child from sleeping is a universal tale which has been told many times over many years.
"Ours is a Christmas story of friendship and fun between Joe and Moz The Monster, in which Joe receives a night light which helps him get a good night's sleep.
"The main thrust of our story is utterly different to Chris Riddell's."
