Craggy Coast, a dungeon in Explorers of Time, Darkness and Sky, is the first dungeon on the expedition. The dungeon is mostly water/rock, with Pokemon such as Krabby. There is also another dungeon you can go into, Side Path, which adds floors onto the dungeon. You have Bidoof with you the first time you go into it, same with Mt.Horn. The Pokemon there have about 35-42 HP.
