Monster Kid
Yo! I'm Monster Kid, or just MK! in Snowdin, a region of the Underground. I'm wearing a striped shirt, so you know I'm a kid! I'm always very energetic and love to run! Usually away from home, haha! ...Man, I should probably head home. I don't have any arms, and just wear a striped shirt. I wanna make a lot of friends! Oh, and I'm a huge fan of Undyne! Man, she's so cool! I wanna be as strong as her one day! Oh, and I'm good friends with Frisk, a human kid!
