Cooky is a very strong pink bunny with a right ear bending down, his left triangle eyebrow is thick while the right normal one is thin. Chimmy is a white puppy with black ears and is usually shown with the tongue sticking out. They are so different, and yet so similar in two things - hugs and working hard. Both of them like to hug in our fanart BTS BT21 Chimmy and Cooky Hug Sticker.
