Who wrote কাপকেক and রামধনু Factory?

I have written the story, Breaking the Fourth Wall, and I want to credit them, because I have used some of their ideas, দ্বারা blended them in this huge mesh up of that world. The intent of this story, is to tell a back story where all of our বন্ধু have been controlled দ্বারা a curse created দ্বারা someone they are all familiar with.
