⚠️ THESE LYRICS ARE NOT OFFICIAL.
The real official Splatoon lyrics can be found in the Splatune and Octotune album booklets.
They are written in hiragana and katakana, but serve only as pronunciation.
The words have no meaning and are only meant to sound like Japanese.
Through an illusion called auditory pareidolia, you can mishear real language in the gibberish.
These lyrics are my personal interpretation.
