Japanese Mystery Kanji / Radical

I'm trying to improve my reading and grammar skills by playing the JP version of Animal Crossing: Wild World, and I've come across a kanji I can't find anywhere. I've tried using the IME pad and the kanji by radicals search on Jisho.org, but neither turns up anything that looks like it. The closest I can find is 戸, but it should have a vertical line going through the top horizontal line and down to the bottom horizontal line of the square. Does anyone have any idea what it is?

Describing it in this manner is unlikely to get you anywhere, as it could be any number of things that are either being missed or are not in the character as it is displayed.

Did you write down or can you replicate the sentence that it came in? In 9/10 cases, the appropriate character can be guessed using nothing but context.
