Stan the Jabberwocky is based on the Jabberwock from Lewis Carrol's poem "Jabberwocky" from the sequel to Alice in Wonderland "Through the Looking Glass"
Like most adaptations, the creators falsely assumed that the creature was called a Jabberwocky, while in the poem it is revealed to simply be called "The Jabberwock"
Stan kidnaps the Princess of Wonderland, whom the Care Bears must rescue.
