Okay, after hours and hours of exploration, I have finally completed the Associate of Baubles, World 2 achievement. So, what follows is a rough guide to the zone, covering only secret rooms and baubles you must collect.
I will not cover Dig Spots: I did almost all of my exploring on Infantile Mode (though I did complete the World on Normal on my very first run, any sort of extensive exploration was going to make lots of use of the Shortcut Clouds…) I also recommend getting this achievement on Infantile, simply because it makes mistakes a lot more lenient. The only problem with Infantile Mode is that keys will not drop from monsters. I don’t know if Chest Baubles count towards the achievement, but I collected them just incase.
On further note with regards to what counts or not, Hillbilly Stills, Raccoon Stumps and all breakables do not count towards Associate of Baubles.
Anyways, let’s begin.
===
Area 1
Ignore the shortcut cloud to start with, and climb up towards the two Waterfalls to the left of the cliffface. The rightmost of the two Waterfalls can be walked through, leading to a room filled with Waterspouts. Climbing up to the top of this room leads to a [RED BAUBLE]. (Before the latest patch, I had visited this room several times and the waterspouts did not exist. I know they were there back in April, so I don’t know what was going on here. If they don’t appear for you, consider restarting your run.)
As you climb up towards the first checkpoint, you will pass by those two Waterfalls again. This time, the leftmost Waterfall can be walked through from the rightmost stone on it. Behind here is a [YELLOW BAUBLE].
Area 2
As you take the normal path through this area, you will come across [4 BLUE BAUBLES] right in your path.
Area 3
Again, the [BLUE BAUBLE] in this area is directly in the required path through the area.
Area 4
[4 BLUE BAUBLES] dot the bridge across the chasm.
Area 5
There are no required baubles or secrets during the raft ride.
Area 6
The first shop is to your left after the Checkpoint. If you’re playing on Infantile Mode, then you should buy a Key here.
The Petal Thrower in front of the Crocodile will throw you across the chasm to a [BLUE BAUBLE]. You should then drop down onto the ledge below that contains a second Petal Thrower. Use it to throw you into the center of the waterfall: if you aim right, you’ll find a secret area with a [YELLOW BAUBLE]. You can then continue climbing up through this secret area to find a [BLUE BAUBLE], [GREEN BAUBLE] and the first chest which contains a [RED BAUBLE] if you managed to bring the Key with you.
Immediately after getting the chest, you can cross over the high ledges where the Toads are, and backtrack a bit to get a [BLUE BAUBLE]. After this, there are some Petal Throwers up here that will help you get towards the next Checkpoint.
Area 7
No baubles to worry about here… yet.
