For your first prompt, write a poem about feeding a monster (or monsters). Be as conscientious as @mctreeleth is by providing skeletons with calcium and avoiding curses from pottery shards. Or if you are feeding a vampire, be thorough: does your vampire need a particular blood type or prefer to use a Capri straw to drink?
For a second prompt, write a list of five innocent hobbies, such as birdwatching or coin collecting, and make a second list of monsters and mythical creatures. Look at the two lists and see what connects for you. Write a poem using one item from each list.
For the last prompt, write a poem using the photo below to describe what happens next.
Good luck writing! Have fun with your monsters!
