It's from a game called "Kobito Zukan: Kobito Kansatsu Set" (こびとづかん こびと観察セット). I don't know much about it, but it looks crazy weird. So, naturally, I want it. XD But it'll never get localized... ._.I'm receiving another new stationery today, from a friend. Neither of us are sure where it's from but he thinks it may be Animal Crossing related. He could be right, but I can't say for sure. It's got bugs all over it.
Here's a trailer:
The friend who sent me the stationery also said he thought it might be Animal Crossing, lol. The game does kinda look like some bizarre mix between Animal Crossing, Pikmin, and The "Denpa" Men. XD
