"What is that?"

"It's called a jetpack! It shoots burning fuel downward, which generates an opposite reaction force upward, and I can angle the direction to steer." She demonstrates by doing a barrel roll.

"...okay!"

Ms. Frizzle flies into one of the larger flowers with a "come over here" gesture. They're small enough to both fit inside it easily.

Assuming Promise can fit inside easily without getting anywhere near her personal space, she'll go into the flower.

At this scale, the flower is the size of a large room; Promise can stay on the far side of stamens bigger than she is. Ms. Frizzle is excitedly pointing out all the pieces of flower anatomy and their functions.

Promise is willing to learn about flower anatomy.

Her explanation concludes with a demonstration of how to scoop some nectar out of the base and drink it. "There's no native sapient life on this planet, by the way, so you shouldn't have any trouble."

"...how do you know?"

"I've been exploring here several times, including well in our future, and never seen any sign of civilization or met anyone who spoke a language. Doesn't rule out microscopic life-forms, I suppose, but even those usually tend to have some visible presence."

"I guess I don't know how a microscopic life-form would be able to give orders anyway..."

She taps her chin thoughtfully. "Yes, if they were telepathic or speaking in radio waves I would certainly have noticed."

"...are there many telepathic things?"

"There's a fair number, but most of them can only communicate within their own species, or with other kinds of telepath. Myself, for instance--I'm technically a telepath, in that I can hear most kinds of telepath when they send things, but I can't do anything with non-telepaths, and some of the people I can hear I can't answer. It's lead to some interestingly structured conversations, now and then."

"I don't want to meet anything that could read my mind."

"Then we can stay well away from anywhere with people who might be able to."

"Thanks."

Ms. Frizzle takes another sip of nectar, then carefully cuts open a stamen and starts looking at the inside.

"What's in there?"

"Interesting tissue structures! I was curious which of a couple other species this flower was related to, and the way the microsporangia are arranged suggests it's most closely related to those ones with the very thin stripes on the petals."

"Flowers are related to other flowers?"

"Yes! On most planets, all the native lifeforms are related to each other. Life starts as one very simple thing, and diversifies over millions of generations of tiny changes into millions of different species." 

"I guess that might be true of the plants in Fairyland if it is of these..."

"Do you know how fairyland plants reproduce? If each new plant resembles its parents, but with some tiny random changes, that will inevitably produce a lot of different but related species given enough time."

"I've never personally cultivated any from seeds, just cuttings sometimes. Some of them are very different, though, like moss and trees..."
