This morning the Disney Store website was updated to add a set of Disney Parks Splash Mountain Tsum Tsums! The set includes the three main characters from the attraction (and corresponding movie) Br'er Rabbit, Br'er Fox, and Br'er Bear as well as the iconic Blue Bird. Rounding out the set are a cute little Possum and one of the Vultures from the attraction.
Here are links to the new Tsums!

Since these are "Disney Parks" Tsum Tsums we expect these to also show up in Walt Disney World and Disneyland soon!
