Dream Dragon Dream

From BoardGameGeek:

Cooperate and frantically search treasure of the Sleeping Dragon! You are a group of adventurers, searching for objects hidden within the treasure of a golden dragon. Each round, players will need to work together to find the objects they need. The dragon's slumber is disturbed by every mistake you make or objects you forget! Loot the treasure for 3 rounds without waking him up, and you win the game! Be careful though, because if you make too many mistakes, the dragon will wake up... and he's always hungry after his nap!
