Tougher enemy, rather than a boss.
Glow, Yellow and Purple Pikmin.
Captain Terras’ Notes:
“Its unusual shell is aragonitic, nacreous and chambered, allowing it a strange means of defense; By altering and releasing the pressure in certain chambers, via the sphericles on its shell, it can create bizarre yet euphonious high-frequency whistles that sound almost like singing.
This creature only becomes active near sundown, where it’ll dig itself up from its burrow, to catch prey using this method; Any organism caught within hearing distance of its song is compelled to draw close and watch, only to be devoured once within range of its tendrils.[NOTE: Practice extreme caution with exploring intertidal flats with high concentrations of sparklium.]
Only one specimen has ever been recorded.”
