USA Pentagon Message is a logo that appears in the NES Video game "Sqoon". This message appears after the title screen of the game before the gameplay demo.
However in the Japanese version, the message came from the United States of America's Pentagon and the message says in Romaji:
SOS...SOS... OTOTOSEIJIN NO SHINRYAKU ARI KYSOKU NI KAIMEN JOSYOSERI SQOON SYUTSUGEKI SEYO KAITEI NI HEIWAO!
And it shows the small face of the man near in the left of the corner.
Medium to Nightmare due to loud noises and the creepy looking small face of the guy in the corner.
