Fish Eater Io Feed And Grow

Take a deep breath and dive down into an underwater world!
Merge, evolve, grow in power, and devour your foes!
This time you will play the role of a little fish to experience the cruel laws of nature's survival. In order to survive, you need to keep eating fish smaller than you and make yourself grow up quickly. When there are dense schools of fish, you have to show great evasion skills to avoid dangerous big fish. In the meantime, even if you evolve into a shark, you can't treat it lightly. Only by evolving into the most advanced whale you can dominate this ocean.
