The Slime, designed by Toriyama for use in "Dragon Quest", has become the official mascot of the "Dragon Quest" series. Series designer Yuji Horii cited the monster as an example of Toriyama's skills, claiming it took " power to take something like a pool of slime and use his imagination to make it a great character." A Slime is a small blue blob, shaped like a water droplet, with a face. It has appeared in every "Dragon Quest" game and it is usually one of the first monsters the players encounter. The Slime's popularity has netted it the "Slime" spin-off series on handheld consoles.
