"Okay, definitely not damaging the only fruit tree I know of. ...Do you know where there are more fruit trees?"

It gives a tiny pointy shrug. {look for shore!} it advises. {forest tree usually oak, sometimes apple. shore tree usually date palm, sometimes coconut palm. careful though! some places dangerous. forest is least dangerous place.}

"How much more dangerous are other places?" 

{mostly not much more, but some very! shadow place very dangerous, blood place very dangerous. if trees bleeding or screaming, is scary place.}

"You know, that makes sense. Which way to the shore?" 

{all ways! is island.}

"...Huh." 

"Since I'm much squishier than you, I'm going to stay here and do experiments that only rely on reasonably available materials." 

"Okay. Do you want me to tear down some more trees so you have wood to work with?" 

"Yes, please." 

"Okay." Tentacles lash out and destroy several more "oak trees." 

This results in lots and lots of acorns and wood!

And then she shambles off in a random direction, pulling down any trees that get in her way so she can find her way back more easily. 

Forest, forest, more forest...

The grid turns out to be three-dimensional; when she encounters a hill, it seems to have been assembled out of cubes, some of them cut in half on a forty-five-degree slope to fill the gap between levels. Most of the cubes are the grassy forest-floor stuff, but some are bare dirt and some are a rough grey stone.

(There's another apple tree at the base of the hill, a little ways out of her way.)

Farther up the hill, it gets colder, and there's snow on the ground and different (though still fruitless) trees. A creature hops toward her: it resembles the green slime, but colourless, frosty, and sparkling prettily in the sun. (It's also twice as big, the full width of a grid-square.)

She detours to pull down the apple tree and collect everything it drops. 

She eats the frosty thing. 

The apple tree drops two apple seeds, some wood, and an abundance of apples. The dropped apples are in tiny-and-stylized form, but expandable in a similar way to torches although with a much shorter placement range and fewer restrictions on target location.

Conveniently, if she collects up a pile of the same sort of thing and pushes them in very close to each other, they collapse into a single object from which she can deploy the individual instances at will.

The frosty thing tastes cool and refreshing, like a spoonful of snow. There's a hint of sweetness to it. It drops two balls of gel.

Another frosty thing shows up after it, and another after that; they seem to arrive at a rate of one every couple of minutes or so.

She continues snacking on frosty things and spitting out the gel. She pulls down a tree and collects its stuff for Wilbur to experiment with. 

The snowy tree looks like some sort of conifer, and its seeds are little pinecones.

Up, up, up... at the crest of the hill, a solid mass of ice rises above the snowy ground, clear and sparkling like the frosty slimes, devoid of trees. If she climbs to the top of that, she will find a pond and a view.

Supposing that the current direction of the sun is west, she's been travelling northeast. From the pond, a river flows down the hill to the northwest; there's a grassy area wrapping around the snowy hill from the northeast shore of the river all the way around its eastern edge to meet the southern end of the forest on the other side, and beyond the grass is a sandy shore. Southwest of the forest, there is a broad expanse of sand that looks more like a true desert than a mere patch of shore; on the southeast end of the desert, there is a small patch of dense forest that might be a jungle. East of the jungle, and due south of her current position, there is a hill taller than the one she currently stands on, and it's hard to tell at this distance exactly what's going on with it, but it's very... red.

Beyond the shores of this island, there are other islands visible in the distance, some far enough to be hardly more than smudges on the horizon, others close enough that she can see a few details. The closest one is to the northeast, past the end of a long tapering shoal; its nearest parts seem to be all grassland.

She considers this, and then heads down and north towards the grassland. 

In the grassland north of the hill there is grass, bamboo (although she may not recognize it), and exactly three fucking enormous trees. The fucking enormous trees are each two grid-squares across—that's four feet—and taller than the hill, with no branches low enough to be within Lucy's reach.

There is also a grassland slime! It is adorably wee, only a few inches across, and clear and shiny like an adventurous dewdrop.

Cute! She noms it. 

...

Gosh, those trees. She wants to climb one. The lack of reachable branches is inconvenient--and surprising--but her tentacles can get a grip on sheer cliff; probably these trees have textured bark she can use to get a climbable grip?

The dewdrop slime tastes surprisingly sweet.

Those trees do indeed have climbable bark! And they're sturdy enough to support her weight. She can climb so high. Well, all right, not that much higher than the hill, and the view isn't significantly better, but in the treetop all that distance is directly below her instead of hidden in a gradual rise of the landscape.

That is sooooo cool. 

Can she see any other giant trees besides these three if she looks around for them? 

She can! There's a whole grove of them in the grassland on the neighbouring island. And there might be more south of the hill, if they're short enough not to be visible above it.

Hmm. Hmmmm. Yeah, leaving the island without telling Wilbur is still probably a bad idea. Oh well. 

She half-climbs half-controlled-falls down the tree and looks around for more tasty dewdrop things.
