Prompt: An eldritch bear, inspired by H.P. Lovecraft's cosmic horror. This creature, resembling a nightmarish version of a bear, has tentacles instead of fur, and its eyes emanate a ghostly glow. The bear's form appears to be constantly shifting, creating a sense of unease and otherworldliness. Inspired artist styles for this piece might include Gustave Doré, Francisco Goya, Henry Fuseli, Arthur Rackham, or Sidney Sime.
