In 2014, Del Taco the restaurant is doing a Sonic Boom promotion. Their kids meal bags are covered in Boom art & the toy is a "Clash Cube". With the first picture, you can see CG mock-up bags. The side has "Enerbeam Maze" to connect Sonic & Tails. The other side has "Connect the Dots" to complete Amy's hammer & Sticks' boomerang.
The toy with the meal is a Clash Cube. But what is that? Is it plastic or paper? How do you play it? Why are there 48 of them on the promotion? Del Taco restaurant is not in every state. Some fans will never see these bags. Do write in for credit if you have photos of the cubes or know what they do.
