Hond die stiekem heelemasal geen hond is
The sentence "Hond die stiekem heelemasal geen hond is" is Dutch and translates in English to "Dog that secretly isn't a dog at all". It is rather vague and requires further details for the AI to generate a precise image.
Assuming the text is referring to a dog-like creature that isn't really a dog, we can improve and make this sentence specific as follows:
"A life-sized robot shaped like a golden retriever, with metallic silver surface, blue LED eyes, and a rectangular panel revealing circuitry on its side to show that it's not a real dog."
