Finally, I am happy to reveal the prompt to the public! ☺️
Make everything inflated with this prompt:
Process this image in such a way that both the character and the environment around are inflatable toys. Each element of the image should be a separate inflatable toy. Use mate rubber materials suitable for inflatable toys. Ensure everything in the picture looks like an inflatable toy. Make sure that each separate element is realistically inflated, has visible wrinkles, and has seams like an inflatable toy. Please keep the colors of the original image.
