A new Halloween Tsum Tsum set will be released at Hong Kong Disneyland this Fall. The new collection includes Mickey, Minnie, Chip, Dale and Donald which all reverse to their Halloween Counterparts. Below is a look at the new Tsum Tsums courtesy of our friends at Disney Magical Kingdom Blog. Also, no work if, or when this new collection will be released outside of Hong Kong Disneyland. As always, stay tuned. 
Cute! And I got to compliment the advertising team for showing the reversed side with a mirror
