Nachitos

From Walkypedia!

Nachitos are a brand of chips distributed in the Walkyverse, and Walky's primary source of food. There have been a number of story arcs in It's Walky! based on events either caused by Nachitos or focusing entirely on the chips themselves. The latter usually involves Walky's eating of them and the hazards it causes to his health. He ate about 100 servings a day, due to the fact that Nachitos give "1% of the daily allowance of protein, vitamin C..."

In the early Walkerton Klik-N-Play games, the real-life Doritos brand of snack chips filled the role normally performed by Nachitos.
