It's roughly SMW's size for Larry and Iggy. But you may be right.  I just need a set dimension to accomodate up to Ludwig's size [including his hair]. It's quite difficult to accomodate the accurate size of each Koopaling without extensive ASM work. But Roy and Morton fit nicely. If only I had more tile space behind Ludwig's head, I'd be able to do his hair. Dr. Floppy's example may seem ideal, but Larry and Ludwig are a bit messed up. With all the suggestions I've been given, we can all work out a plan to accomodate all Koopalings with theit proper shapes and sizes. And I don't always have to do the open/close mouth thing. I can just simply keep the mouth open

I can give up one or two tiles just for that
