She has yellow eyes like an Hedwig's. Maybe her name is reminiscent of
owls' cliche hoot "Whooo hooo".

*sigh* I was hoping for House Elf, not Goblin. 

And She said : "I must admit, I was taken aback when I saw the film
Flitwick, who looks very much like a goblin/elf (I've never actually
asked the filmmakers precisely what he is), because the Flitwick in my
imagination simply looks like a very small old man." The Flitwick of
MY imagination also simply looks like a very small old man, but notice
the phrase "goblin/elf". We can spin that as Herself hinting that
Goblins and House Elves are related.

pretty common thing in the WW, far more common than some puristas
would like to think. >>

Or to the theory Dumbledore hires professors out of pity for their
inability to get hired for other jobs due to bloodist bigotry, rather
than their teaching ability.
