Unlocked, found, started, played and completed all of Clanker’s Cavern today. That took the best part of an hour! I also found another jiggy in Gruntilda’s Lair, and then made a start (and an almost-finish) of the swamp level – finding 9 of the 10 jiggies. I think I know where the 10th is too, so that shouldn’t take long.
