Phantamanta

The Phantamanta is an antagonist of the Gamecube game, Super Mario Sunshine. It is a strange silhouette that's shaped as a manta ray that leaves electric goop trails wherever it goes. It serves as the boss of Episode 1 of Sirena Beach. Prior to Mario's arrival, it has already covered an majority of the beach in electric goops, and is responsible for the disappearance of Hotel Defino. It was already gone when Mario arrived, but suddenly returned when Mario was talking with the Hotel Manager.

Battle
Phantamanta can only be harmed by spraying it with F.L.U.D.D.'s water. As mention before, Phantamanta leaves behind at trail of electric goop wherever it goes, which is capable of hurting Mario upon contact. Mario must be cautious when battling Phantamanta, as the smallest drop can zap Mario. If Mario touches Phantamanta, it'll deal damage to him as he's being swung back.

When it's damaged enough by F.L.U.D.D., it'll divide into two smaller mantas which each of them dividing into four more smaller mantas, which in turn can divide into four even more smaller mantas. In total, there is 64 mantas that must be defeated.

At first, the smallest mantas won't pursue Mario and appears to run away. However, once the bigger mantas are fully divided, they'll begin to chase after Mario. At this point, there will be a lot of tiny mantas chasing Mario, but these mantas only take one squirt of water to defeat.

When last manta is destroyed, Phantamanta is defeated for good. The hotel will then rise from the ground, and a Shine Spirit will appear, ending the episode.
