mc5 - Animal-Vegetable-Mineral-Abstract: The Pants Memorial Game

The chairperson selects an object/idea/whatever and announces whether it's animal, vegetable, mineral, and/or abstract. The others have to ask questions to figure out what it is. Whomever guesses the object correctly is given the chair for the next round; repeat ad nauseam.

Raak

Albinism?

Huxley

Chalky - not a disorder, no. Raak - no.

Inkspot

Is it associated with a loss of some sort?

Stabbing in the dark, slightly confused.

Chalky

Infertility?

Huxley

Inkspot - no. Chalky - no.

Let me recap the important questions (in descending order of relevance)... as it seems that all are confused...

(1) It is not considered a good thing.
(2) It can be perceieved by the senses
(3) It could not exist without animals or humans
(4) It is not a "disease"
(5) It is not a "disorder"
(6) It isn't unique to humans

and... If you think sideways, Noodle was so so so so so close with his vague question...
As for (4) and (5) you might want to consider a thesaurus.
