Traduzione - Portoghese brasiliano-Giapponese - me decifra ou te devoro

POesia, esfinge

Romanized
Watashi ga dashita nazo ga tokenakattara, anata o tabete shimau.
Literally:
If you can't solve the riddle I have posed, I will eat you up.
---
PS: the LITERAL translation would be
私を解けなかったら、あなたを食べてしまう
Romanized
Watashi o tokenakattara, anata o tabete shimau
but this would be incomprehensible to most ordinary Japanese people.
