The Gremlin design was from Disney, based on a story and description from Roald Dahl, the guy motivated to get gremlins into pop culture from the tales told by British pilots. He was also the author of the many famous books, Charlie and the Chocolate Factory, Chitty Chitty Bang Bang, the James Bond movie "You Only Live Twice", and Matilda... but it all started with "Gremlins" with Disney
The Gremlins was released as a book by Walt Disney and Random House with proceeds going to the RAF Benevolent Fund.
