Sometimes a gooey cube, sometimes a gooey sphere, sometimes a gooey pyramid, and sometimes a gooey person! It doesn't seem to adhere to a gender or an identity of any kind, really, but it does answer to the name "Nijusei".  Perhaps a phrase from long ago, or perhaps a name that meant something once upon a time.

This creature seems to be loyal to a few certain people (you know who you are) and is willing to do anything they command it to do.  It wears clothes sometimes, but usually creatures clothes out of its own goo. Able to discolor its goo, in addition to changing its shape and form...  This creature can do a lot of stuff!

If your character is one that is well-versed in identifying planar creatures sends me a tell and I may have a secrets for you.  

You want to get a surprise?  Let's play then... We'll have fun one way or another. (adventure, shard runs, erp, rp, or whatever)
