I went to Sumida Aquarium with some friends since we were also going to Tokyo Skytree that day.
One of them had never been to an aquarium before either, so it was fun.
I can't remember if I'd been to one either to be honest.
There's plenty of terrible jokes in there, and penguin butt too.
This is basically how my housemates and I act all the time.
Got plenty of stuff I recorded on my holiday back in Japan, gonna be working on getting them out... also I can't make thumbnails to save my life.
