Someone who is very sneaky, like a ninja, yet smooth, like a fish swimming

An actual fish wearing ninja clothes, usually a goldfish.
"Oh man, you snuck up on me, like a ninja fish!"

"Tony:Why did you dress up you goldfish in ninja clothes-its gonna die.
Danny: Yea but i own a ninja fish"

To put red Swedish fish in a woman's vagina while on her period so it makes earning one's red wings a much more pleasant and exciting experience.
Todd went Ninja Fishing on me last night and couldn't get enough of it....now he wishes I got my period more often.
