Today the Japanese Disney Store released some new Toy Story Tsum Tsums! This is apperently to celebrate the 20th anniversay of the release of Toy Story (even though its actual release date isn't until November).
Included in the new Tsums are medium versions of Woody, Buzz, Hamm, and Three Peas in a Pod as well as a new set of three mini Little Green Men/Alien Tsums in a rocket ship. The other two new releases are Lotso and Alien in a massive new Tsum Tsum size XL.
These were released today in stores and will be available June 18th on-line
