Ah am sorry folks, but no Derpy again:( I'm having troubles with it (both mentally and physically).. I don't know.. Every time when I'm trying to make ep. 4, there's a lot of problems, which leads me into depression.
So, I switched my activity and now I'm making... Luna game! Yes!
p.s.: for those, who wants Pinkie Pie and her trombone: there is no 50 votes, so it have to wait, ok?:)
