Since this isn't a race she's less careful with keeping to plausibly Amentan biology. (Her floofy skirt also never gets in the way, the same way her limbs never get in the way.)

Whee! Onis hangs upside down by her knees and signs "Are those human clothes?"

"Yes! Though I changed some pieces!"

"They're funny looking!"

"Amentan clothes look pretty funny to me, too!"

"You'll probably get used to them!" And then she must use her hands to climb more!

Bright climbs as high as she can!

The structure goes pretty high! There is a part that they can get up to via a sort of ladder, one pole with steps sticking out into the air on either side, and an entertainingly wobbly two-child-sized basket at the top, in which they can sway.

Now that they aren't racing her limbs are sometimes instead tentacles, which really helps with climbing! And her dress sometimes moves in a way that isn't gravity or the wind, mostly so it doesn't tangle or get caught.

Balancing in the wobbly basket is hard! It keeps falling towards Bright, who giggles at this.

"Oops," signs Onis, giggling, "I forgot you're heavy - I think this can hold a lot but maybe it's not a good idea -"

"Yeah, probably." She climbs out.

Down they go. "I like it up there," Onis signs when she drops to the ground, "you can see a long way down the street, all the way to the park with the carousel."

"It's neat. I haven't been to the park yet!"

"It's a good park. There are ducks in the pond sometimes."

"I'll have to go maybe!"

"You can feed the ducks, they'll come right up to you if you do!"

"Ducks on Earth are like that too! There's also a squirrel on the university campus who'll eat right out of people's hands. It's super fat!"

"Why's there just one?"

"Squirrels are usually really scared of things bigger than them, and they're only this big." She holds her hands apart demonstratively. 

"Awww. That one squirrel will probably have a bunch of baby squirrels though. What do squirrels look like?"

She makes one on her arm! "This is a normal squirrel..." It's pretty thin. Then it changes: "And this's the fat squirrel!" It's easily three times the width. "Fat squirrel still won't let people pet it though!"

"Maybe its baby squirrels will!"

"Maybe! I dunno if it has any, or how old it is even... Mom thinks people shouldn't feed it though because it's already really slow and squirrels need to be fast to get away from bigger animals, but students don't listen to professors about that."

"Are there a lot of bigger animals around?"

"Yeah. Dogs are really big - the smallest are bigger than the fat squirrel and the largest are as big as an adult human - and lots of humans have dogs as pets, and there are feral dogs in some places. Dogs chase squirrels. And there's hawks, which are big hunting birds. And there's cats, which I think are too small to usually hunt squirrels but some might, and they're really common around humans. And there's foxes, which are this big..." She holds her hands apart. "Foxes are my favorite animal! There's a family of foxes that lives under our house back home! If you aren't in the city there's also wolves and mountain lions and coyotes... And some humans hunt squirrels, but that's mostly a rural thing."
