3D rig of an original character inspired by Fred from 'Courage the Cowardly Dog.' The character should have a quirky, eerie appearance with exaggerated features such as a wide grin and slightly unsettling eyes. Ensure the rig includes fully articulated limbs, a flexible spine, and detailed facial expressions that convey a sense of peculiar charm and mild creepiness. The character should wear simple yet distinctive clothing, and be in an A pose.
