The first-ever Kwik-E-Truck opened for business at SXSW Interactive last weekend and served more than 3,400 free Kwik-E-Mart Squishees to festivalgoers over two days.

Created to celebrate the Kwik-E-Mart’s inaugural appearance on "The Simpsons" 25 years ago the food truck will now travel the U.S. with the next stop yet to be announced.

In addition to Squishees, the truck offers interactive photo experiences, branded iPads with the new “Simpsons World” digital platform, which features every "The Simpsons" episode ever, and offers a sneak peek of the upcoming Kwik-E-Mart LEGO set.
