Fish-Man Island was wrapped in a light yet resilient Sun Tree bubble, making it a floating island that could drift anywhere.
So Garen planned to first bring Fish-Man Island to the waters near Wano Country, the League of Heroes' temporary headquarters, and settle it there. Once the fish-men decided where to permanently reside, or if the League of Heroes moved its headquarters in the future, they could pack it up and take it away at any time.
However, after carrying the heavy Fish-Man Island, the Float-Float Fruit's flying speed slowed considerably.
Once its speed dropped, the floating island vaguely began to resemble a sightseeing yacht:
Bright sunlight poured down, making the Sun Tree bubble surrounding Fish-Man Island refract dreamlike seven-colored rainbows.
The fish-men, who had always lived beneath the sea, had never seen such dazzling light. Shirahoshi, who had been confined in Hard-Shell Tower since childhood, was even more curious about it.
"Lord Garen!"
Shirahoshi excitedly linked arms with Garen and pointed at everything she could see, asking question after question:
"Is that the bird from the legends?"
