In the center of this vibrant, kaleidoscopic birthday card scene, a fantastical fusion of cartoon characters from across the multiverse gather in an exuberant celebration to craft a sprawling sign that reads "HAPPY BIRTHDAY GEORGE." The characters are nestled within a floating geometric realm inspired by Piet Mondrian, where primary-colored squares and rectangles intermingle with curved lines and spirals reminiscent of Wassily Kandinsky’s playful compositions. Emerging from a nebula of abstract forms akin to Jackson Pollock’s energetic drips, beloved characters like Bugs Bunny and SpongeBob SquarePants work alongside lesser-known figures like Gumby and Felix the Cat, each contributing their unique flair.

Mickey Mouse, elevated on a ladder made of interwoven pastel hues, diligently paints the letter "H" with a brush that drips with polychromatic splatters reminiscent of Cy Twombly's chaotic yet controlled gestures. Below, Scooby-Doo and the Smurfs laboriously roll out a cerulean canvas strip to form the letter "A," while Daffy Duck and Yogi Bear tussle over a surreal brush, turning the letter "P" into a deconstructed dreamscape echoing Joan Miró’s whimsical forms. A trio of Minions, clad in their usual denim attire, unspool vibrant ribbons that twist and twine around the letters like Mark Rothko’s ethereal color fields, while Tom and Jerry playfully chase around the evolving masterpiece, adding comical lines and splashes.

In the sky above, a fleet of abstract, cloud-like shapes inspired by Kazimir Malevich hover in asymmetric harmony, casting shadows of varied blues and oranges upon the characters below. Agnes Martin’s delicate grids subtly frame the border, creating a sense of infinite expansion, while Willem de Kooning’s dynamic strokes form a background of vibrant chaos, suggesting the underlying energy that fuels this multiverse assembly. The entire composition is a vivid tapestry of vibrant hues and lively interactions, each element intricately detailed, creating a jubilant, surreal landscape that celebrates the joyous occasion with imaginative flair.
