McDonald's promised to "make things right" with miffed "Rick and Morty" fans and bring back its coveted Szechuan Sauce.

"Instead of being one-day-only and limited to select restaurants, we're bringing more -- a lot more -- so that any fan who's willing to do whatever it takes for Szechuan Sauce will only have to ask for it at a nearby McDonald's," said the company.

Fans of both the show and hot sauce were outraged Saturday when they descended upon their local McDonald's in search of Szechuan Sauce for McNuggets and came away empty handed.

The chain's October 7 event featured the sauce, which happens to be the favorite food of Rick, the mad scientist character from "Rick and Morty," an irreverent cartoon from the Cartoon Network's "Adult Swim." Time Warner (TWX) is the parent company of both the Cartoon Network and CNNMoney.

Supplies quickly ran out when hordes of rabid "Rick and Morty" fans descended on McDonald's restaurants in Welllington, Florida, and also New York City, where ComicCon was underway.

McDonald's (MDNDF)admitted that it didn't anticipate the fervor.

"Our super-limited batch, though well-intentioned, clearly wasn't near enough to meet that demand," said McDonald's in a statement. "Not cool."

That pledge is a big reversal McDonald's original plan. The day before the October 7 rollout McDonald's said it would release a "one-time only, limited edition, run of Szechuan Sauce in select restaurants. And when we say limited, we mean really, really limited!"

But spurned "Rick and Morty" fans lit up Twitter with complaints about going to McDonald's and getting turned away sauceless.

But other customers complained on Twitter about the "savage" and "insane" behavior of the "Ricky and Morty" fans. One fan reportedly threw McNuggets at an employee, a report that wasn't independently verified by McDonald's.

The Szechuan sauce, which was featured in a recent "Rick and Morty" episode, is a favorite of mad scientist Rick.

At the end of the episode, he says he's driven by finding that McNugget sauce. "I want that Mulan McNugget sauce, Morty," says Rick. "That's my series arc, Morty. If it takes nine seasons, I want my McNugget dipping sauce Szechuan Sauce, Morty."
