What are your worldbuilding strategies?

I'm curious about how you guys come up with your world's creatures in particular.

Do you just randomly get an idea in your head and add lore to it? Do you get inspired by some show and try to make something similar? Do you draw some random stuff and then add lore? Or is it something else?

I'm curious about knowing what works best for you and how you discovered it was best.

Feel free to tell me about your creatures as well.
