If you really want to put the other one in, then I'll only send it to you, but only if I can have both of them in. You said it wouldn't be fair for me to have two and you to have only one, but that's why you can think of an idea to make another one! Like I said, ninjas are always cool ;)
Okay, I'll type the original one in, and I'll made one.
Now let's do it like this, and this message is for ALL OF THE MEMBERS OF THE COLLAB:
Everybody will do one part. If 15 parts will be short (less then 2 min or something) I'll tell everybody make another one and so on. But let's start with one.
