You can use world edit, to start with, do //wand. Then place a block down. On this block, place a ladder, vine or flowerpot. Left and right click the block and do either //cut or //set 0. For a lily pad, place down a water source and put down a lily pad on it. Left and right click the lily pad and do //move {number of blocks it needs moving} whilst looking in that direction. Hope this helps. Chicken
