Phantamanta

"This giant manta-shaped thing showed up. It was this paper-thin...floating silhouette. It came and covered the hotel grounds in this electric goop."

- Hotel Manager

Phantamanta, or simply Manta, is a boss in Super Mario Sunshine, who appears in the first episode of Sirena Beach. It is the cause of the Hotel Delfino's disappearance. It is a pale pink silhouette of a manta ray, and its name is a pun on "phantom" and "manta". When Mario sprays it with water from F.L.U.D.D., it splits into smaller versions of itself. It possesses the uncanny ability to project itself over any surface of varying elevations instantaneously, much like a shadow.

Wherever Phantamanta moves, it leaves a trail of teal and yellow electric goop, which Mario can spray with F.L.U.D.D. If there is even a tiny drop of it left, Mario can get zapped when he touches it. Areas where the Phantamanta cannot reach Mario are if he is under one of the two huts or under a coconut tree. In addition, if Mario stands in the water, the Phantamanta can still reach him, but cannot produce goop with a shock. Upon contact with F.L.U.D.D.'s water, Phantamanta first divides into two. Each of those Mantas can divide into two more. Each of those divide into four Mantas. And, each of those can further divide into four more Mantas, making a total of 64 Mantas to defeat. When all of the Mantas have fully divided, they will turn purple, become irate, and start swarming towards Mario; until this point, the smallest Mantas do not pursue him, but all the larger sizes will. Once the last one is vanquished, Hotel Delfino will be restored, revealing a Shine Sprite for Mario to collect.

Trivia

 * Phantamanta's music is a slightly eerie remix of the boss music that plays when fighting the Plungelos and the Polluted Piranha Plants.
 * In Mario Golf: Toadstool Tour and Mario Golf: Advance Tour, one of the default names on the scoreboards is Phantamanta.
 * Phantamanta may have been inspired from the ending of the horror novel The Shining: "a ghostly manta shape, floating away over the hotel. It was paper thin, like a shadow, and then broke into smaller forms before turning into smoke and drifting away." * Phantamanta and the smaller Phantamantas are also diffrent around Mario. Also Phantamantas have diffrent effects on Mario. The largest usually follows him, and moves very slowly, and as the Phantamantas get smaller, they increase in speed and aren't very aware of Mario until they turn purple.
