"Wow, a talking tree!" Bruce whispers.

"Whatever you are--MAKE ME A PIZZA!"

"O-kaaay. I'm guessing this is a thing that makes pizzas?" Bruce reaches out and pokes the "peppers" button, and when this results in the image at the top changing to a peppered pizza he pokes that too. It's like a touchscreen made of rocks and that's trippy and fantastic.

The machine whirs and churns and spins its gears and emits a pizza, complete with plate, onto the ground.

"Well, that's going to be handy for keeping us fed," Speeba remarks.

"It really is! Anybody want a slice of this one?" He's been trying not to eat like a person ten times the size of everyone else despite in fact being that and could honestly eat the entire thing right now, but there is such a thing as manners. He looked in the machine as it was working and he's pretty sure there's a lot more where this came from.

"Hey, uh, you," Speeba says to the talking tree, "do you want this pizza or can we have it?" It seems only polite to ask.

"Bring it over here so I can see it."

They carry the pizza over to the tree for inspection. (The Lands of Logic are a weird, weird place.)

"There's something on that I don't like!"

Is this how tree-people behave when they're being polite, Bruce wonders, or do other tree-people find this one obnoxious too? It's very convenient how the first species he met is one that's easy for humans to get along with.

What he says out loud is "Okay great, ours now."

"Yep!" says Speeba. "You can have it, I bet you're the hungriest one in the group. Let's try feeding the tree something else. Plain, maybe?"

"Sounds good." He rolls the pizza up like a degenerate burrito and takes a bite, then generates another one in plain.

Arno reacts to the plain one with a wail of "Moooore toooppings!"

Speeba sighs. "Try something different, I guess. I'd do it myself but you've got an undeniable advantage at reaching the controls."

"Yeah, between the human faces on the cliffs and the UI on this pizza machine, I'm starting to wonder if there are more humans around here somewhere." He orders up a cheese pizza and, yup, that sure does look like cheese materializing out of nothing inside the tower. Vegan cheese pizza alert?! Best bonkers puzzle continent.

Arno continues to want MOAR TOPPINGS. 

Bruce continues to manufacture MOAR TOPPINGS. At one point the pizza machine jams up and Bruce has to stick his hand in it to remove a wodge of dough from the dispensing mechanism, but its ability to generate tasty ex nihilo matter still puts it in the 99th percentile of machines Bruce has interacted with.

Eventually Arno is satisfied by a pizza loaded with Literally Everything Except Peppers. He even manages to thank the delivery Zoombini graciously before eating the entire thing, tray and all, and there are enough uneaten pizzas that everyone can have as much as they want before moving out.

Speeba leads the expedition onward in a much improved mood. Unlimited pizza will do that.

Onward they hike through beautiful uninhabited wilderness. The sun sinks towards the horizon and the light turns golden on the trees. Just as it's getting on time to make camp before they lose the light, they reach a clearing shaded by a single enormous rock, with a generous overhang making a pocket sheltered from the weather. 

Zoombinis park and make camp and eat dinner and settle in for the night.

Bruce has very vivid dreams about evading rock-monsters who want his pizza and takes a minute, in the morning, to sort out which implausible things probably actually happened and which implausible things definitely didn't. Breakfast is pizza again and he is not going to think about the infernally catchy Weird Al song nope nope the sun is a mass of incandescent gas a gigantic nuclear furnace . . . okay, time to set out. 

The terrain gets very steep and densely wooded due east of here, but they can angle either north or south around it.

"What do you think, Kwisp?"

"South!"

"All right, south it is."
