James is asking: Who was Big Mouths Girlfriend?
It was Big Nose. There was one episode where Big Nose ditches Big Mouth because he has “no romance, no manners, and no future,” and goes out with some ogre named Big Teeth. Then Vanity Smurf and Smurfette (and some others) teach Big Mouth to be more romantic and have better manners, so he wins Big Nose back. There was another episode where the Smurfs painted the sleeping Big Mouth’s toenails as a joke, and when he wakes up he is mad, but then Big Nose sees the painted toenails and insists on having the Smurfs paint her toenails, too.
