A moment later.
The sacred Evolution Light faded.
Goomy—no, the drastically transformed Hisuian Sliggoo—revealed its brand-new form.
Its once horizontally spread body had been stretched much longer, as though made of putty. Looking even more like a snail now, the four antennae on its head had grown longer, replacing its ears and nose as Hisuian Sliggoo's highest-performance radar, sensing sounds and scents.
The green spots on its cheeks had shrunk, while their color had deepened.

It subtly affected the mucus on its skin, and when Goomy evolved, part of that mucus transformed into a metallic shell.
But to the Goomy clan on the island in the middle of the lake, all of this had long since become commonplace.
They did not know what form their
