Advice to the Cookers:

xxx: Well, once such a drunkard has gone, advise the acid or other chemistry to pour into the pot, in which six months ago the chicken turned into NGYARCHHY, to reclaim from NGYARCHHY the pot back.
YYY: Hm... we had a half-semester in the pot compartment with pasta inside. Six months later, when it was remembered, a civilization derived from pasta used toxic gas in an attempt to invade the territory of the pot and establish contact.

Do not use napalm. The story of the film "Evolution" can be repeated. Ideal is nitric oxide. He will not only untraceably erase the NGYARCHHH, but also the pot.
