Apart from the regular ingredients in the burrito, you can add a packet of SPICY POP ROCKS to the mix for a 20-cent addition to the $1.29 price. They add a sweet-spicy flavor along with a fizzy texture to the burrito, but be warned: too many of these popping candies at once could make the burrito taste way too sweet, which, as I've learned the hard way, is not a pleasant feeling.
