Sonic Chocolates are a specialty from Spain, Earth. They come in a vast spectrum of beautiful flavors, colors and packages, ranging from strawberry yogurt to shrimp ramen. Very few humans have heard tweets about these Sonic Chocolates; the chocolate bars are mainly imported to other planets for residents to enjoy and remember all the heroic actions Sonic (and Sanic!) has done for them.
A Sonic milk chocolate bar (literally filled with sweet dry milk) was mentioned in the "Sanic Civil Wars" scene were Marx and Ame are both seen eating one in Alex Jones's TV show talking about triangles and loominarty.
