So I asked my spouse to give me something weird, or a monster, to sketch... and here you have it! The Amikiri. It is said to be "a small snake-like creature with a bird-like head and lobster-like claws".

Banded sea krait (although a lot of the other depictions shows a more lobster/shrimp like body, I went with that description!), lesser sand plover head and the limbs of Metanephrops japonicus.
