Clues.

For the great password
You must look in the game
And decide which word
Every funkey has in its name.

Next look for me,
I look like a Rhino
But I am not he.
I dwell in the water
Just like an otter
Also, I have no horns.

Now put the two together
Fuse them into one,
And what is left over?
A not-so-funny pun.
