I can never think of titles, so they will be nonsequitors when I feel the urge, your only warning.
My big discovery today was this cool little hunt. It’s in front of Wynx Whiplash’s tiny store. I was there to buy a bunny but that’s a story for another time.

When you land there’ll be a big pool there, dive in, the adventure begins *hollywood Titanic-style musics*
It’s not too difficult of a hunt, depending on how diligent you are and on whether you cheat. 
The prize is nice but the real fun is just the environment. I’ve done a LOT of treasure hunts and this one was special because of the atmosphere, they really took the time & did it right. It’s a whole undersea adventure, with creatures & caves and whatnot. Go do it, take a friend!
I love Japanese stuff, you all know that, and purikura machines are right up there. Purikura is “print club”, super fancy photo booths where you can get custom backgrounds and frames and stuff right on the photos. SL has them and they’re pretty cool.

This one is in Nipponbashi. Cam into the booth a little (they’re kind of cramped) and choose one of the 5 pose stands (bring some friends for more interesting pictures!) and then use page up and page down to scroll through poses. clicking on the front screen will change the frames and clicking on the back will bring up a window with options for backgrounds. you can mix it up, when you’re ready just do a snapshot as usual and you can have a cool Japanese-style purikura picture souvenir! This particular booth is catty-corner from the zombie shooting game so grab a gun & have some fun in Nipponbashi. I plan to do some more things that focus on fun stuff to see & do in Japanese sims.
EDIT ADDING
I saw this at SLU and had to share. Gummi Lighthouses-candy gone wrong
