Sometimes animals lose control and attack.
A runaway animal can be brought back to life by covering it with a bucket of water.
Run away without getting caught until you get water.

Borrow their abilities by clearing the missions requested by animals and befriending them.
Escape from this mysterious facility and get freedom.

Various trials await you.
