Sorry do you have a link or anything because Iron Tail was a TM from Gen 2 - 4 so anything that had it as an egg move just wasn't changed when that move became a move tutor move. It's like Scyther and defog, you need a compatible parent who was taught that move via HM from gen 4 then passed on up. They're not moves that were move tutor moves that are also egg moves, they're HM/tm moves that were egg moved then when that move was removed from the TM/HM list then became a move tutor move that still is the egg move. Sorry to keep on this, but surely a list must have been compiled somewhere, there's got to be a better method that going through the history of every single egg move of 300 - 400 pokemon lines just to see which ones trace back to a th/hm/move tutor from gen 4 or even gen 3. Is there any links that are a little more comprehensive?
Also, speaking of lack of clarity, does anyone know how much the berries heal your HP? There's numerous berries that are listed as being able to restore your HP but will cause confusion if the pokemon hates the taste, yet the sites don't seem to actually state by HOW MUCH HP is restored. To me, "restore" means full HP recovery while "recover" would be a small amount, but surely these berries don't restore that much, do they? Does anyone know? Thanks!
