Here I am! Captain of the Holy Palanquin Ship, Captain Murasa!
You lot! Today we're going smashing again with my ass anchor!
(A-a A-a Aa-!)
|eng2=
Anchor! Anchor! Ass anchor!
Anchor! Anchor! Ass anchor! (Aah!)
Anchor! Anchor! Ass anchor!
Captain Murasa's ass anchor! (Aah!)

Leave any troubles with water to me!
I'll get to the "bottom" of any situation in a snap!
In other words, I'll completely remove
The source of the leak, smash it at the roots!
|eng4=
Captain! The toilet! It's all blocked up and the poop won't flow!
Is that so? I'll kill ya! Give me my anchor!
Captain! The baths! We can't peek in the women's 'cause of the steam!
Oh, really? I'll kill ya! Hand me my anchor!

Anchor! Anchor! Dragging anchor! This anchor sinks ships to the bottom of the sea!
Anchor! Anchor! Dragging anchor! This anchor s-s-s-sinks 'em, right?<ref>Chin-chin is Japanese slang for the male genitalia. This joke is also more apparent in the PV.</ref>

Will soon be sunk by its tough appeal!
I wedge it all the way in, and all
The fat, hard-struggling punks get dragged along!
|eng9=
Captain! The faucet! It's broken and the water won't stooop!
Is that so? Death for you! Hand me my anchor!
Captain! The pool! It's too crowded for us to see the little girrrrls!
Is that so? Death for you! Hand me my anchor!
|eng10=
Dragging anchor! Ship sinking anchor! This anchor goes to the bottom of the sea! Dragging that s-s-sinks 'em and r-r-r-r-really hurts em', right! No! It's still a virgin! I am going to re-educate you! Captain Murasa's Ass Anchor! (Aa!)
