Jawling = in the north section of Russet Highlands, there is a ruin with piles of leaves. The one in the back right corner has a hole under it. Go down the hole. You'll want to twine with a member of the jawling family, as it runs away if it sees you, and you need their vision ability to get rid of the rock. There is a bug where sometimes the vision puzzle isn't present, but the rock is.
Helmwhelp = there's a chest up on one of the platforms in central russet highlands, he's guarding it. More spawn by the sanctum just below after you deal w him.
Helgon = flying around above the chest the golden helmwhelp was guarding.
Helmut = there's a regular helmut just west of the clear sight sanctum, worshipping a golden helmet. Use magnet hand to move it, and it'll turn into gold helmut. Now they spawn naturally at night.
Rookey = on a ledge above snow rookey's spawn. Night time only, AFTER moving the gold helmet from the gold helmut condition.
Snow rookey spawns on the raised platform where the regular non-alpha catchable rookey hangs out, southwest of the clear sight sanctum during snowstorms (hiding in a snowball)
