Mochi!Sealand X reader

You saw a little sailor hat popped out of the box along with a white little head with thick eyebrows that suspiciously looked like England's. However, England don't wear hats like that so it must be a little one that related to him. Also, it looked younger yet still similar so you guessed it must be Sealand. My, this will be quite a handful though you don't mind children much. As you expected, the little Sealand mochi greeted enthusiastically.
                                        "Hey, nice to meet you!"

You named the little one "Peter" and he was like any energetic little boys, or mochis. The little one practically like sprinting around the place and was quite a little rascal. For example, sometimes he just liked to prank people, which resulted in you becoming the first victim. His first try was water, then bugs and many more that you became accustomed to it. Therefore, your expression remained unfazed the more he tried on you and more experienced in blocking off the traps when he tried it on other people.

Of course, you tried to distracted him from creating such pranks by letting him watch TV and stuff. Of course, at a limited time though sometimes he was too attached to the TV that he ignored what you had said. You needed to find something to break that concentration, you heard that the Sweden mochi is an expert of it with the box thing. Yeah, maybe you should try that, or just turn off the TV. On the other hand, at least it seemed little Peter learned a lot from television as he really liked plays and of course cartoon like Spongebob.

The interesting thing is that he's somehow really good at history, but denied it...
