The cover art to a book released in 2001 adapting the movie of the series.
When Magic Adventures of Mumfie was aired on Fox Family Channel in the United States and Nick Jr. in the United Kingdom during the late 90's, one of the tie-ins to the airing was a book called "Meet Mumfie!". Little is known about this book except for listings on various websites such as Amazon's UK site with a mispelled title.
