Frito Lays Crunch Tators were hot and spicy jalapeno potato chips with a really hard crunch and were available around the late 1980's and early 1990's. There was an alligator on the front of the bag. The two flavors were: "Hoppin' Jalapeno" and "Mighty Mesquite BBQ".
A bag of the "Mighty Mesquite BBQ" flavor chips can be seen in Home Alone next to a can of Pepsi in the scene where Kevin is watching Angels with Filthy Souls and eating a rather large ice cream sundae.
