In "A Sitch in Time," Rufus sadly pulls out a packet of Diablo Sauce from a fallen Bueno Nacho.
In "Day of the Snowmen," Ron used the 5-Alarm Diablo Sauce to keep his hands warm in the blizzard. Rufus used all of the sauces to melt several of the toxic snowmen.
In "So the Drama," Ned wrote "Evil" on a tray with the sauce as a message to Ron.
- Diablo Sauce is possibly based off of Taco Bell's Fire Sauce. On May 5, 2015, Taco Bell actually created a sauce of the same name.
