{can make floor from wood and wall from wood and chair from wood! can make torch from wood and gel, and lamp from wood and torch!}

Putting his hands on the crafting table doesn't do anything extra, but being near it seems to unlock a whole bunch more wood-related recipes. The new ones have a tag indicating that they are crafted at the Crafting Table.

Neat! He'll just make one of everything he can make with only wood, then, until he runs out of wood or recipes or runs into something dangerous to have a miniature one of.

All together, including things he previously made, this leaves him with:

a fence, a floor, a wall, a thick wall, a door, a wide door, a beam,

a helm, cuirass, boots, gauntlets, and greaves,

an axe, a pickaxe,

and 1 remaining uncrafted wood.

All the items start out in tiny form, but can be expanded according to their category: placeables can be placed, wearables can be put on, and tools can be equipped to wield. The axe and pickaxe cost 2 wood each, the door and wide door he made for 3, and everything else cost 1. There seems to be one remaining uncrafted item in the tool category, none in the wearable category, and plenty more in the placeable category.

Of placeables he could make using wood alone, two cost 2 wood, two cost 4 wood, one costs a variable amount with a miminum of 2, and two cost a variable amount with a minimum of 3. All those require the crafting table; he has exhausted all the only-wood handcraftable recipes except for that one remaining tool.

"Thanks, spirit! This is cool stuff!" He puts on the armor, expecting that it will somehow fit him perfectly and be wearable despite being made of wood, places the walls at right angles in a clear space, and attempts to cut down another tree with the wooden axe.

His expectations about the armor are accurate! It's surprisingly comfortable, too.

The axe is highly successful at cutting down the tree; the first five chops each take out a single small chip from the trunk, and the sixth causes the whole tree to dissolve into a rain of tiny logs. Now he has more wood, and a couple of little acorn items which turn out to place little saplings.

Ooh, he can do sustainable forestry, if that's even a concern here. He plants the saplings nearby enough to keep an eye on them but out of the way of his two walls worth of pre-house.

"How do trees grow here?" He asks. "What would have happened to those acorns if I hadn't cut the tree down?"

{plant tree, tree is small. tree is small, is small, is small, is small, then tree is big! tree gives seed sometimes when cut. before cut tree, no seed.}

"So they only reproduce when they die, then? Huh."

More house-building! Four walls and a floor. Four thick walls, if he can pick the thin one back up: he knows there are hazards about, and even if thick walls won't necessarily provide more safety they probably won't provide less.

He can pick the thin one back up if he tries bopping it with a tool of some sort; the axe and the pickaxe both work for this purpose.

The thick walls are about a foot thick; the thin walls are about four inches. Thick walls seem to align most naturally with their edges along the edge of a grid-square, whereas thin ones seem to prefer standing centered on a gridline.

Bruce puts his crafting table in his house. "Would you like to come in?" He asks the forest spirit, while trying more recipes in search of a roof. He also recalls chairs being mentioned; one of those would be nice too.

{okay!}

It toddles cheerfully into the house and sits its round little self down in a corner.

The full list of things craftable at the Crafting Table with only wood turns out to be:

a chair (2), a bench (2), a bookcase (4), a chest of drawers (4), a table (n>=2), a bathtub (n>=3), a bedframe (n>=3), and the beam he made earlier (1).

Also, if he tries it, the remaining handcraftable wooden tool is a hammer.

Possibly he will have to use floors as ceilings and make that his roof. Or he could ask the creature about other options.

The existence of bookcases suggests the existence of books! Everything is significantly more okay than it was a minute ago. He puts up some bookcases and makes himself and the spirit a chair each.

The chest of drawers and bathtub are good in and of themselves, but remind him that wherever he is doesn't have plumbing and he's going to need to learn to make soap and find water somewhere.

Also he is definitely going to try using a floor as a roof just to see what will happen.

The spirit is so delighted to sit in its chair. It is comically tiny in comparison to the size of the chair, but seems to be just fine with that.

Using a floor as a roof appears to work without issue!

Also, when he places the bathtub, it appears with a bar of soap sitting in the little soap dish built into the rim near the faucet. The faucet is made of the same wood as the rest of the tub, and although there's no discernible input hookup, the knobs look like they'd turn if he tried them.

Awwww, the forest spirit is so cute! He's glad they're easy to please, especially since they might well be the only other person in this reality-or-possibly-the-opposite-of-that.

Spontaneous soap, huh? Weird, but thank goodness. He turns the knobs. Does water appear out of nowhere? Conservation of mass has already gone out the window, fallen thirty stories, and splattered on the pavement, so it might as well.

Water does appear out of nowhere, or at least out of nowhere that's physically attached to this bathtub. And then it flows down the drain and goes right back where it came from. There's a little wooden cork-thing to plug the drain with.

That is extremely cool. All of this is cool once you get past how terrifying it is; it's like he's exploring a whole new set of consistent but alien laws of physics. If this isn't real, it's the most interesting hallucination he's ever heard of. If only he had memorized a hundred-digit number to ask the forest spirit to factorize. 

More prosaically, he's thirsty. "Is this water safe to drink? And do you know where it comes from and where it goes?"

{comes from bathtub. goes to bathtub. is bathtub water. is safe, I think? am not water spirit.}

"There are water spirits? What are they like? What other kinds are there? And I'm curious about forest spirits too--are there lots of you, do you have cities somewhere. . . ?"

{is just me here! and water spirit in water and stone spirit in cave and cloud spirit in sky.}

"Only four of you? Are there people around who aren't spirits?" If there are only four people, either this is a really tiny place, or it's surprising he ran into someone so quickly, or . . . "Did you know I was going to come here?" Did they bring him here?

{knew there was going to be friend! didn't know when. long time alone first.} It doesn't seem too upset about that, though. {just spirit and animal and monster, no friend.}

Awwww he's their friend! But the rest of that was concerning! "How did you know? And what are animals and monsters?"

{just knew! know lots of things. animal is animal, does animal things. moves around, sometimes drinks water, sometimes eats grass. monster is monster, does monster things. tries to hurt animal or friend or spirit. is scary.}

"Shit--I mean, uh, yikes." Swearing in front of this dude is like swearing in front of a small child. "Do you know how I can keep us safe from the monsters?"

{monster can't open door!} it says reassuringly. {can build house, be safe inside. most places only have scary monster at night. scary places have scary monster in day. blood place and shadow place are scary. if trees bleeding or screaming, place is scary, stay away. other places, in day only monster is slime, doesn't try to hurt you until you touch it or hurt it. also scary place very very far underground and very very high up in sky. and can make weapons, fight monster! but is scary.}
