Equestria Crossover confusion 2 Hunt for Celestia

So yeah my recent work has been to get the first chapter of this story ready for action but it's been a little difficult trying to write for many reasons, one of the biggest needing to keep editing it to match what I write at the end of Equestria Crossover Confusion 1, yeah still got a few idea about how I want to end it. The story will be an opposite of what the first was, the ponies this time will be travelling to other worlds to rescue Celestia, rather than characters coming to Equestria but many challenges await. New friends, enemies a plenty, new worlds and a surprise round every corner! However here's the question hands up who wants worlds that have had characters visit already, so the likes of the ponies travelling to Redwall where Basil Stag Hare is from? Maybe go to the Pokemon world or see if the digimon will accept them. A lot of this is a long way off because I have to finish the first story before I can upload the first chapter of the sequel but the sooner I have an idea of what I'm doing the better. The first world the ponies are going to do is already decided, their opponents will be friends and enemies at the same time, the ponies will have to draw on new skills they may not have to win! (Celestia! I hope that wasn't too obvious)
