Everyone should be prompting safely while staying hydrated, so why not combine the two and turn that watermelon you have rotting in the fridge into a proper helmet?
Trained on way too many (140+) pictures of animals/people/AI things wearing watermelons as hats/helmets. Another old meme has been revived for your prompting benefit!
Just modify the following prompt and you're good to go (or remix from my examples):
melonhelm, (character/species/person/etc.) wearing watermelon (hat/helmet)
