One of Nathan Explosion's endorsement deals, Explosion Sauce is a North Carolina style barbecue sauce with a mustardy blend and a hint of cilantro. Nathan loves the sauce, drinking it straight from the bottle. Unfortunately, Skwisgaar Skwigelf is allergic to cilantro; having any contact with it makes him have an anaphylactic reaction that shows as swelling and redness on his skin. It's unknown what Rose and Oscar Explosion think of their last name being used for a product or whether they like the sauce itself like Nathan does.
