From the entrance, head south until you find two Plasma Grunts. Assuming you've cleared the Plasma Frigate earlier, Hugh will show up from behind, and then the Plasma Grunts will head off, following the direction of another one that shows up. After some dialogue, Hugh will run off, and then the Plasma Grunt will head on after him (although nowhere near as quickly).

Push a boulder right nearby to create a minor shortcut, but more importantly give you access to a place you can Surf on. Surfing to the north there brings you to the valuable TM13 (Ice Beam), which is a top-notch Ice-type attack to teach your Pokemon.

At where the water started, head west (there are a few ways to get there, but they all take you to the same place) until you find a big hole leading down into the ground. Those steps are where you're going to want to go in just a moment, to reach the forest, but there's still a lot more to explore in the cavern part of the Giant Chasm.

So head south and west instead. The door leading out actually takes you to the original entrance to the Giant Chasm in Black and White. There's a hidden Moon Stone on the bridge to the north, plus there's a Yellow Shard out in the open not too far away from that. Out of the hole and then to the south and west, through the patches of grass, you can find a hidden Max Potion that you might as well pick up.

South of that will take you back onto Route 13, where you can shove a boulder over with Strength to create a shortcut back to the Giant Chasm, which is very convenient so you can get there from Lacunosa Town. There's also a hidden Heart Scale in the rock down the stairs to the south, as well as a not-so-hidden Hyper Potion in the sands by the stairs. Additionally, you can find a Hidden Grotto over by the stairs.

Return to the entrance to the Giant Chasm (from the Lacunosa side), then head west. There's a hidden Star Piece in one of the rocks down a small flight of steps. Pick that up, then head further west and north until you see a boulder you can push. Push it and you can get a Max Repel.

Head north for awhile and you'll find some Team Plasma Grunts blocking the path onto Route 23. They're not going to leave until after you've tracked down the Plasma Frigate, though, so leave them be for now and keep heading north. There's a hidden Ultra Ball in the northwest corner, plus there's another boulder you can push to get to another Star Piece.

Keep going west and push another boulder down to reach a hidden Ice Gem. Further east just takes you back to the entrance. It's probably quicker jumping down and going around than going backwards, so you might as well. Jump down there and then make your way to the hole in the middle of the southern part. That'll take you out to the forest!

As soon as you enter, Hugh will be there, as well as the Ex-Team Plasma and the newer Team Plasma. It appears they're having quite a bit of a standoff. Rood is trying to convince them that Ghetsis' way is wrong. Hugh then breaks up the fight and gets the Plasma Grunts' attention, forcing them to fight you and Hugh, although individually in Single Battles. The one you'll fight has a Weezing L47 and a Muk L47.

Rood will give you 3 Max Revives after your fight. After some more dialogue, Rood and his faction of Team Plasma will hold off the new faction, instructing you and Hugh to track down the Shadow Triad and stop them in the Plasma Frigate.

Just to the west of the showdown is a Razor Claw, which raises the holder's critical hit rate, but it can also be held by Sneasel to evolve it into Weavile if it gains a level at nighttime, which is convenient, since you can catch Sneasel inside of the Giant Chasm caves. Head north of the Plasma Grunts and you'll find another Moon Stone just sitting out in the open for you to take.

Alright, now go in after Hugh and enter the icy part of the forest. It's a slippery surface, so you'll slide up to the north. When you get up there, climb the stairs then slide east, north, west, and then south. That should get you over to where the Plasma Frigate parked.

Frigate Frenzy!

Depending on whether you're playing Black 2 or White 2, the puzzle and layout of the upcoming Plasma Frigate changes quite drastically! Make sure you view the section that corresponds to your version, otherwise you will be quite confused!
