A zoo has been taken over by monsters and you have been tasked with entering this zoo, finding the cause of the monster infestation, and putting a stop to it. To accomplish this task, you must collect key shards that have been scattered throughout the zoo. To find the key shards, you must solve puzzles within the animal enclosures. Once all the shards are collected, you can assemble the master key to unlock the source of the monster anomalies.
