New Tamagotchi Event!
The above link shows some "Idol Park" or something in Japan. The pictures might be indicating a new Tamagotchi-themed addition to there, or maybe even representing the whole thing as a new addition (I'm not sure, since I can't read it)!
By translating the page on Google, I saw that it must be a new Tamagotchi park after all. It seems to be themed after Lovelitchi/Lovelin from the anime, and involve things like wearng dresses, dancing with someone in a Lovelitchi costume, stuff related to acting like a pop star or something (Nothing I'd really be interested in, of course... ).
