This game includes occasional use of mild bad language (‘bloody’).
Other issues
The fish characters encounter some dangers, such as sea gulls or humans attacking them or the containers in which they’re housed. It is also possible for fish to suffocate if they become stuck in rubbish.
In one scene, a piranha has to bite a number of blood sacks in a hospital, in order to fill the room with blood and allow the fish to escape. The ensuing tide of blood sweeps away a human.
In another scene, set in a nightclub, there is sight of lines of white powder with a straw next to them. While this suggests drug use, there is no sight of drugs being used.
