Shrink and Carry the Box Out Your Own Shrinkray Adventure chapter 6 by Marak077

You shrink the box, held it around your arm and take it out to give it to Catherine, telling her that this box was causing all the racket, you saw an opening where a noise came from it after all.

Of course that was a lie since you didn't want to tell her about the raygun, you also manage to lie that you close that gap as well. A gap that never existed in the first place.

"So this thing is what makes all that racket? A box?!" She commented, she couldn't really believe it at first seeing it in her hands, but after it suddenly shakes and makes that familiar sounding noise she heard before. She nodded, confirming the source of the problem. "I'll have to dispose this later. I dunno what it is, but it's certainly not safe. Well, it feels like it. But I'm not gonna open it."

She throws the box next to her, and looks at you. "Thank you so much! That's one less problem to fix, you don't have to worry about the other ones though. While you're out, I did have someone solve the other issues." She explains, and you simply nodded, happy to help a neighbor, is what you said.

"Well, I am free to do anything else in the meantime. How about I give you a reward, my treat!" 

You asked about the reward.

"Anything! Well, anything reasonable."
