Morty knows he shouldn't be screwing around with multidimensional shit. It's dangerous, it's impractical, it's blah blah blah. But it's a potential key to unlimited energy, how does nobody see that? He's built a dimensional siphon (it kind of looks like a cardboard box with a funnel and a TI-84 taped to it, but it damn well works), keyed in the dimensional coordinates to a random plane, and by God he's going to use it.
He flips the switch and waits for the energy bar to fill up.
It does! It fills up very rapidly. Then it explodes, along with the box. There's rather more smoke than there should be, and once the smoke clears someone is standing there.
"Whoops?" Morty says faintly.
"They like to make sure."
Morty shows her into the Campus Store, where she can purchase toiletries, bedding, clothes, several different sizes of porcelain water pitcher shaped like cows, throwing knives, or a wide variety of other Earthly material goods.
"Oh wow. Oh wow," she says at the array of Earthly material goods. "Okay, what's the currency here and how many of it do I have in the account this is hooked up to again?" She waves her card.
"Currency here is dollars, a hot meal is ten to thirty dollars, you have I think it's ten thousand of them right now, that's a lot because you have to start a new life here et cetera and, again, being very nice. You can reasonably purchase pretty much anything in this store without having to worry about it. Prices should be listed."
"Do I need to pay for food? Does the account get replenished or do I need a job by the time I need more?"
"Food is included in your free tuition unless you go into town, but the food in the cafeteria's actually really good. The account gets a thousand dollars a week."
"Gosh, okay. Is there more tour, I don't want to make you follow me around while I'm shopping if you have other things to do -"
"There's not really more tour but I don't have anything else to do right now, it's afternoon and I'm kind of a boring person. Besides, I'm a helpful resource if you get confused about anything."
"Great, I appreciate that!"
She begins browsing, filling a basket with a sheet set and toiletries, holding up clothes to herself to see if they'll fit, totting up prices in her head.
"It's weird that this plane also has jeans and t-shirts," she says. "Is there a fitting room?"
"It's pretty weird, yeah, ours are totally made with science. Fitting room should be right over there."
Bella tries on jeans and t-shirts. "Am I like to run into any situations when I need something more formal?" she asks, finding everything eerily well-sized and getting duplicates of a couple things.
"Maybe? There's like, dances and stuff, plus you might just want to be fancy at some point. - oh, and you'll need a karate gi unless you're taking Survival instead of Basic Martial Arts, that's a thing."
"Huh, I actually don't know. Normally you're not allowed to wear shoes, but they're kind of an assistive device for you... You'd have to check with Sensei Tolman, I think. I can do that and get back to you tomorrow?"
"Thanks. I'll hold off on the martial arts clothes till I know if I can do martial arts." She rummages through nicer clothes and picks a nice dress.
"Thanks." She tries it on. "Why does everything I try on fit?" she asks, coming out in her original extraplanar jeans and t-shirt and tossing the dress in the basket. "I assume if I tried on the stuff that obviously isn't my size it won't, but anything that looks about right if I hold it up is perfect!"
"The Campus Store is weird, I think there's enchantments on it. It also has weirdly precognitive stocking, whenever you're looking for something really obscure they usually just got it in. That kind of stuff is above my paygrade."
"Gosh. Well, it's really convenient. Okay, what do you have in the way of crystal balls, or science crystal balls...?"
"Might need to know what a crystal ball is. I mean, they've got literal orbs, some made of crystal, but they don't do anything for you if you're not a wizard."
"I'm not a wizard, I just know a handful of spells. Crystal balls browse the ethernet and let you 'scape presentations and documents and art and ethernet sites?"
"Oh! You have magic computers, that's... strangely charming. Also very convenient. We call those 'computers,' the secretary gave you one, it's the rectangular plastic box? We have an internet instead of an ethernet, ethernet's just a way of connecting to the internet, it's confusing, but otherwise it sounds pretty much the same. The Whateley-issued laptop is all-around decent and pretty much indestructible but not top-of-the-line in any other way, plus it's firewalled so you can't get to, uh, certain sites, so if you want a better computer they are over here." He shows her to the computer section.
"Oh, okay. Why is it a rectangular box? And I don't know what the specs are in comparison to crystal balls so I don't know if I'll be disappointed - what's the science version of ether gazing to do stuff on it -?"
