Nyar Spider/Mad

The Nyar spider is fascinating. Is it intelligent? A tool-user - is it perhaps a tool fabricator? (No stores stock spider-size cutlery.)

It has "facial" expressions. Perhaps Agatha shouldn't kill it after all. It might be another Krosp-like construct and have something to contribute.

Besides, if they keep it from eating her, it seems to have found a useful solution to the problem of Zola.
