What do you call the tuft of fuzz on a pony's chest?

Hmmmm I can't quite put my finger on it....!

Fuzzy wozzy chest pillow. That seems like it.

Woof! Man, that feeling just pulses through you! Who needs the hard stuff when you got a Fluff Addiction, eh?

  I do like the idea of a Chest Crest.

 Really hadn't pegged Rainbow as a fluff gal, nor have I with Rarity. She does seem almost brittle with as well groomed & trimmed she keeps herself! But man, she is a mare of many styles! Could really use ourselves a revisit back to Hairity!

Nice...plumage.

I always call it Fluzz; a combo a fluff and fuzz.  Simple as that.
