"My condolences. And yes, most of the time it is obvious, but you don't want to get down to the last bit and realise you should have eaten that in two bites instead of one because now you don't have any left," he explains.

"Is there a minimum bite size?"

"No, I don't think so?" he says uncertainly.

"I've never really tested it."

Dinner is apparently ready; he sets an array of dishes on the table and calls Everless. 

...she picks one and takes one bite.

Nothing immediately obvious happens.

"Might not want to do that," Hatter remarks calmly, digging into his own food. 

He gestures at her hair, which is turning green and growing rapidly. 

She giggles and takes another bite.

The changes revert. Hatter snorts.

"That one was fairly safe, but I'd advise against doing the same thing with the beef," he says. "Starts turning you into a cow, which is fine except for the part where cows aren't so great at eating meat."

Everless flies in and perches on the back of a chair so she can reach her food.

"Any other hazards like that or can I experiment to my heart's content with everything else?"

"Potatoes will make your fingernails grow, apparently," Everless contributes. "I wouldn't know, since I don't have any. The carrots, you have tried, and I believe the beans make one thinner."

She rips off a chunk of beef and holds it in her claws to munch at.

Well she'll try everything!

These foods have the stated effects!

The beans feel like being squished narrower, rather than like weight loss. All of the changes are trivially reversible, assuming she heeds the warning about the beef, and she can even use different sized bites of potato to customise her nail length if she wants.

Her nail length's fine, thanks. And this is way fun!

If Wonderland were aware of her sentiments, it might be flattered that she's enjoying its features.

Hopefully not so much that she forgets to be careful when she gets down to the last few bites, though.

Oh she only experiments once per food, after that she counts her bites.

In that case, she will not end up with green hair or black and white spots at the end of the meal.

"It's getting late," Hatter says when they have finished eating. "You should get some sleep, Sadde. I've arranged a lot of meetings for tomorrow."

He shows her the room he has cleared out, which is small and sparsely furnished, but adequate. There are still a few hatboxes stacked in the corners. "I don't get many visitors," he apologises. "I hope it will do."

"It'll do just fine. Thank you very much for your hospitality."

"You are very welcome," he assures her.

"Do you need anything else before you sleep, or shall I see you in the morning?"

"I believe that will be all, thank you very much, kind sir." And to punctuate it she curtsies.

He laughs, bows extravagantly, and departs.

Well. Sleep it is, then.

In the morning, Sadde is woken up by the weight of a cat climbing all over the bed. 

"Wake uuupp," a familiar voice meows. 

He opens his eyes and blinks. "Good morning, Chess. How are you doing?"

Chess kneads the blanket and purrs.

"Good morning, Sadde. Araminta wants to meet you."

He doesn't seem inclined to let Sadde get up, though, curling up and settling down on top of him.

"I do need you to get off me so I can get up," he says when that becomes clear. "Could you bring me a grape?"

"Oh, I suppose," he concedes, jumping off the bed and padding out of the room.

He's back a few minutes later with a small bunch of grapes, held in his mouth by the stalk, which he deposits on the nightstand. 

"This was the easiest way to carry them," he explains.
