Create a Shrek-themed rubber duck designed for Jeep ducking. The duck should have the recognizable features of Shrek — green skin, friendly ogre face, small round ears sticking out from the sides of its head, and a soft grin. The body should keep the classic rubber duck shape and size. Outfit the duck in Shrek’s brown vest, white tunic, and brown belt, but simplified to fit the duck’s rounded form. Use smooth textures like rubber or soft vinyl, with slightly glossy surfaces. The style should be cute, fun, and collectible, ideal for gifting or dashboard display.
