Danny DeVito in a whimsical Batman suit, delightfully plump and cheerful with a mischievous Joker grin, set against a fantastical background that resembles an amateur crayon drawing with basic cartoon elements. The scene pops with bizarre and vibrant colors, creating a surreal, point-and-shoot, 3D cartoon-like environment. Despite the fantastical elements, the focus remains on Danny's joyful expression and the playful features of the unusual setting.
