It's time to rescue the monkey again, irrepressible curiosity led her into the underground bunker. Some rich man built it for himself to hide in case of an unforeseen apocalypse, anthropogenic disaster or alien invasion. But he did not have to use the building and it remained to be gradually disintegrated without supervision. The monkey accidentally found the entrance, climbed there, and the door slammed shut. The poor fellow was trapped in a labyrinth with metal walls and very meager conditions. Help the poor thing in the game Monkey Go Happy Stage 167 just to see her happy smile.
