What is grizzles logo?

As an AI language model, I don't know what grizzles logo you are referring to without any context, as there are multiple entities that use a grizzly bear mascot or have "grizzlies" in their name. However, generally speaking, a logo is a visual symbol or emblem that represents a brand or organization. A logo can be designed to communicate a company's values, mission, or products and services. Grizzlies logos often feature a fierce grizzly bear, typically in shades of brown and tan, with sharp teeth and claws, and a determined expression. Some logos may also incorporate the team's name, initials, or mascot in the design.
