Piano Lessons can be murder" For some reason, this guy is very funny to me, they don't even TRY to make him scare, you can sort of tell because he knocks into several walls while chasing the main character. He's VERY over the top. He looks like Santa Class if he went crazy, and became a Piano Teacher. In case you're wondering, he's played by Aron Tager. For now, he is my all time Goosebumps Character of all time.
