Applebloom loves being a filty messy filly. So she goes to the outhouse on her farm and crawls inside the outhouse. She starts wallowing and covering herself all with pure messy filty stinky poo.  
when she got fully covered in scat. She hears somepony entering the outhouse. It was her big sister Applejack who needed lose some bricks.
 
Applejack sat on the hole and starts pooping fresh smelly diarhee all over Applebloom. Applebloom really liked that and cathed some of the green diahree poo and smeared some on her face
