Horn, Tusk. W-w-whatevah.

Little Miss is a talker.  She's a great one- She can tell you "all 'bout it", no matter what it is.  Her vocabulary is extensive, and the only verbal vestige of Her babyhood is the "R"s.  Little Miss can say Her Rs, but She mostly doesn't.  Generally, She omits them altogether, giving Her speech a unique mixture of Boston and southern belle.  She pahks the cah.  She gets Her heh done.  And Her fingah nails.  Words that start with R pose a particular difficulty, and tend to become Ws.
Combine this quirk with Miss's distinctive tenacity and, well.  For example:

Miss and J were playing with a sensory toy, in which objects beginning with the same letter are grouped together.  They were working on W.

J: "What's this one?"

Miss: "A W-w-wAHgon."

J: "Yes! And this one?"

Miss: "A W-w-wAffle."

J: "How about this one?"

Miss: "uuhh, that one? Hmm.  Oh! I know.  It's a W-w-wi-nocerous!"

J: "But it has to start with W."

Miss: "Yes it IS start wif a dubbah you.  W-w-winocerous."

J: "Um...no I think it is a walrus."

Miss: "Dad.  A walus isn't a aminal.  That's. a. wi-nocerous."
