A sketch of the lower half. What kind of front part would fit this boss best?

Made a fun sketch of the lower half of the final boss for my ASCII game. The motion is fully procedural. Everything is calculated in real time.

Does the movement look interesting?

Now I need to make the front half really weird and cool.

What kind of front part would fit this boss best?

P.S. Also working on a fix for the hieroglyph bug. Thanks for supporting the project!
