First, I am able to find the stats for all of the leshys except Vine Leshys. The race entries say that you can grow them and lists the requirements and costs, but they don't have a stat block. Do you use an NPC array of some sort? When you add extra hit dice to them or any other grown Leshy can they take class levels?
Second, when growing them the math isn't entirely clear to me. It sounds like all Leshys have a base cost + 2250 per additional HD but then immediately says (4500 to the overall cost)? That reads like a typo that is missing part of the example perhaps? I am unable to find any good examples of the crafting costs.
