The military lab
The military lab symbolizes destructive human activities in the ocean. The military uses Google for experimental purposes without taking care of him. Goggle lives in captivity most of his life because humans use him for their benefit. The military uses big ships and tankers to transport goods to their military labs. Oil spillage from tankers makes the sea inhabitable, thus endangering sea creatures.
The pod
The pod is a symbol of peace and stability. Ea lives in the pod with other family members. Despite her disability, Ea is treated well by other pod members. Other dolphins consider the pod a holy place where each member deserves respect. Dolphins believe that by treating others well, they will live a productive life.
The oyster
The oyster symbolizes mutual benefit. The oyster attaches himself to the body of Ea. Oyster feeds on Ea's blood to survive. However, the oyster is a significant creature in Ea's life. For instance, the oyster helps Ea to understand his surroundings. Since Ea cannot hear ocean tides, the oyster guides her in what direction to take whenever they walk together. Consequently, these two friends have a mutual benefit because they depend on each other to survive.
