The stitch (Carnophascolarctos terriblis), also known as the killer koala and the blue koala, is a species of marsupial of the koala family Phascolarctidae that originally did not exist, but has since been created by SciiFii due to demands for more types of pets, and this animal was created as inspired by the famous Disney character of the same name. The stitch is a rather large koala, growing to be about the size of a medium-sized dog, having the shoulder height of between 22 to 24 in (56 to 61 cm) and weighing about 29–34 kg (65-75 lb). The male stitch is largely greyish-blue in color with patches of hairless pale skin on the chest and belly, while the female is pale-pink in color with less hair than the males. Unlike most koalas, the hands of a stitch has only four fingers and don't have opposable thumbs, as the stitch has been modified to be mostly terrestrial in a manner more akin to dogs, which the stitch is often mistaken for. The stitch is a carnivore, unlike most koalas, feeding primarily on carrion, insects, lizards, snakes, frogs, and man-made food made of meat, although they are known to occasionally feed on eggs and birds. The stitch is a solitary animal towards members of its own species,
although the males get along very well with females, the males can be aggressive to each other, so it is best to keep the males separate from each other. The stitch is a strong marsupial, being nearly half as strong as a chimpanzee, somewhat stronger than a person. Despite this, the stitch is a generally docile, friendly, and loyal animal towards people. The stitch is popular to the pet owners who are fans of science fiction movies.
