The underwater world of mermaids

After an accident, you found yourself in the underwater world of mermaids and realized that you had become a mermaid. After examining your new body, you were in complete shock when you saw a beautiful mermaid tail instead of legs.
When you swam to the bottom, you saw a sign with different tails that indicated what kind of mermaid you were. There were different types of tails: 1-angel mermaid, 2-fallen mermaid, 3-regular mermaid, 4-coral mermaid, 5-flying mermaid, 6-pearl mermaid, and 7-fan mermaid.
