What is this thing invading my mouth?

There's this horrible, sharp thing that's forcing it's way through my gums and I don't know why it feels the need to do that but I think I'll just scream until it stops. Mommy gave me frozen peaches in my mesh feeder which helped but I couldn't take my nap this morning, my gums hurt too much. She finally nursed me to sleep around 12:30 which is an hour and a half later than I usually sleep.

Before the wicked thing overtook my gums, I was in a good mood, playing, dancing to They Might Be Giants, being a goofball. Hopefully this tooth thing won't last long and I can get back to being my usually self.
