This Friday, we play as Marvin and must battle against Night Evil Jeffy who looks an EXE. The whole funny mod is based on a site that shows creepy things related to SML. This mod includes a bunch of scary songs that you can play for weeks, but without boyfriend (BF) and girlfriend (GF) as usual in some songs. However, Jeffys Endless Aethos Music Battle still is a love story of BF and GF but in horror way.
