1. The politeness levels in this song shift back and forth frequently. It is not something I can easily translate.
2. This is a pun as it can also be translated as "Because sex isn't bad."
3. This can also be translated as "I always enjoy the look of fright."
4. Torotoro is the sound effect of something oozing or dripping; I took a little liberty here with the translation.
5. The TV size version has them talking in the beginning, but this is not in the full-sized version. The paragraph below is this conversation (taken from the fansub.)
I wonder what I should do today
To excite you and turn you on
I'm having fun already just thinking about it
I'll show you that I'm the luckiest one in the end
Come on, let's all fight until we're all melted
Oh, Swamp Witch
What an eerie existence
Well, we're all girls of the underworld
Oh, Swamp Witch such erotic actions
We'll truly show our love for you
The three of us will all serve you
But of course
Girls, let's do our jobs properly
