Splatoon is really popular with 3rd-5th grade boys atm especially! Every time there's an art project, at least one or two squids sneaks in there.
But these properties come and go all the time, so the older teachers have become experts at ignoring that shit as much as possible XD
Meanwhile I'm waiting 'til I get back to the US to grab a WiiU and try it out .__. I promised myself I'd only get portable consoles here~
