Jazz Jackrabbit

Jazz Jackrabbit is an arcade-platform game starring "a little rabbit with a big gun." The game's protagonist is Jazz Jackrabbit, a green furry hero on a quest to rescue Princess Eva Earlong, who has been kidnapped by the notorious (and nerdy) leader of the turtle terrorists, Devan Shell. The game was included (as the 6-episode version) with some copies of Jazz Jackrabbit 2. (The first run did not come with JJ1 due to some error, and instead had a slip of paper with a phone number that could be called in order to request the game.)
