Umi no Triton EP6 - Go to the Southern Island!

Triton and his friends are heading for Dolphin Island in the South Pacific Ocean. Poseidon orders Poripeimos, commander of the South Pacific Ocean, to chase Triton and his friends. Poripeimos attacks them with a huge lantern anglerfish that uses sound waves as a weapon. Triton enlists the three dolphins Iru, Karu, and Fin for support. Their decoy plan works well, and Triton's party makes a narrow escape.
