A new WcDonald's Sauce arrives, and fans everywhere get excited. Studio Pierrot's four short episodes each borrow a major anime genre: action, romance, mecha and fantasy. In the first, two strangers race each other to be the very first to taste the new sauce. In the second, Kazuki and Shizuru find that sauce and WcNuggets are not the only good match, and they have to face their growing feelings. The third moves to a WcDonald's on a moon base, where the crew boards the giant robot WcDizer 3000 to protect the sauce from a hungry monster called the Wakudon. In the last, three friends sharing the sauce during its final week are carried off to a magical land, where they must find the sage Kenja to keep it from disappearing.
