Startled clingy blob's opinion: "...Mom they know we're here, we should talk, humans don't usually say they just want to talk right? And they think we're aliens not shoggoths, aliens aren't bad things in their language."

...She will stop sneaking away but will form a human head and torso on one tentacle to lean over the edge of the roof to look at them. Does she get shot at?

Nope! "Thank you!" says the grey who's been talking. "Are you hungry? Do you need some food? We can get you some food."

After Bright translates that...

She takes a deep breath through her breathing-membranes. Normally, she'd leave Bright hidden, and go herself, but that damned Elder God gave her child the language power...

"Bright, I'm going to carry you on my back so we can talk to them, but you need to run if they try to hurt me, okay? Run, and not look at what's happening."

There's a little twitch of tentacles against her side - somewhat like a nod.

She retracts the human-seeming and swarms back down the side of the building as a mess of tentacles, turning into her previous purple Amentan shape at the bottom. She doesn't really settle her skin as fast as she usually does - she wants to see if they offer her violence for being strange. (Bright is still clinging onto her back as an orange blob.)

Translated through Bright: "I don't know your language. My child does. Why would you offer food?"

Nausicaa translates this as "Mom doesn't know your language but I do so I'm translating. Food's good but why're you offering?"

The silent grey takes a half step back but doesn't draw a weapon or anything. "...well, that's what's been reported stolen," says the talkative one.

"Sorry. I'm not good at digesting non-food plants yet but we didn't know how the money worked and mom didn't wanna say we weren't Amentan right away even though stealing's wrong," Nausicaa volunteers before their mom can finish thinking, but after translating the thing to shoggoth-tongue. 

And then, for their mom: "We're from a place where the main species is humans and they don't usually offer people things."

"Our world's been hoping to meet aliens for a long time. We can definitely get you food if you're hungry."

"Why do you wanna meet aliens?"

Humans mostly seem to really not like all their non-human neighbors but maybe that's because a lot of the historical cases had someone being hostile? But the other peoples Nausicaa's familiar with are mean slavers or reclusive types like the shoggoths and Deep Ones. Maybe there's a whole species of people who like making friends like her! 

(This is a slightly bouncy small orange tentacled blob.)

"We want to learn more about the world," says the grey who's talking, "and aliens would know different things than we do!"

Quick fluting conversation with mom, then: 

"We don't want to be made to do stuff, but we can trade telling you stuff for food and places to sleep and knowledge about here. Not all stuff, since some things are really dangerous to know, but stuff that's helpful?"

Nausicaa has won the 'we shouldn't act hostile and should be friendly to get off on right foot' argument. 

"We'd be happy to get you a place to sleep and some food. Is a hotel good?"

"Yeah! I can be Amentan shaped too, should I?"

"That'd make it easier to get you into the hotel without a lot of people noticing."

Then she's an Amentan purple girl again!

"Do you want to ride in the backs of the scooters?"

After another argument in the shoggoth language: 

"Only if we can ride together, mom doesn't wanna split up. Oh and mom's super heavy so I don't know if your scooters would break?"

"- how heavy?"

"Mom's the density of water when she's normal big and her mass doesn't change? I'm about twice the weight of a human kid my size, I think Amentans are built like humans, and uh... Mom's like thirty times my weight? I'm really far from being done growing..."

"Okay. We can scoot slowly and you can walk."

(The quieter grey murmurs into his radio.)

"Okay! I like walking places."

The scooters putter along at walking speed till they reach a hotel lobby, oddly crowded for the hour including with a couple greens and a blue, and are provided keys to a room and a bag of assorted groceries.

Food! And a very curious apparently purple alien child who is listening in on people's conversations!

(How do the keys work, are they fancy technology?)

The keys are magnetic strip key cards! The people are talking about how at this hour it is difficult to get more people.

How do magnetic strip key cards work? They're used to physical keys that're made of metal and you stick them in a lock and turn them, and the key cards don't seem like the really fancy stuff she knows some places use?
