mc5 - King AVMA the III

[Tuj] Entirely non-metal.
[Rosie] Not a prosthetic.

Is it a building?

[Chalky] Not a building.

Would it float?

The very original of it that the pedant above tried to bring up might indeed float. But the thing is otherwise not something that can float or sink.

I am also thinking that "yes" and "no" are both misleading answers to the uniqueness question.

Recap

So far we know that it doesn't begin with 'P', isn't metallic and not a building.
