Recently, their new "billboard" advertisement went up, broadcasting the party, which will be taking place from May 19 all the way through June and finally coming to a conclusion July 6.
The billboard advertises different costumes that will be available to members, featuring characters from the film! The character costumes advertised on the poster are Lieutenant Judy Hopps, Nick Wilde, Assistant Mayor Bellwether and Officer Clawhauser (from left to right).
It seems the costumes look very movie-realistic, as if Zootopia is actually Club Penguin. This makes me very excited to see the final product of the Zootopia Party!
