Chili dog

Chili Dogs are hot dogs with chili sauce. They are the favorite food of Sonic the Hedgehog in several continuities, particularly the various TV series: Adventures of Sonic the Hedgehog, Sonic the Hedgehog (SatAM) and Sonic Underground. Recent games from the series have also made reference to chili dogs as Sonic's food of choice. In Adventures of Sonic the Hedgehog, Tails also liked chili dogs, but preferred his with extra cheese.

Other types of hot dogs also appear. For example, in Sonic Underground, Sonic's sister Sonia the Hedgehog likes to eat hot dogs with tofu.

The earliest canon reference to Sonic's enjoyment of hot dogs (rather than the more specific chili dogs) seems to be in early issues of Sonic the Comic. In Sonic the Comic #5, Sonic sits down to eat 300 hot dogs and 100 thick shakes as the second course of breakfast (the first course of which consisted of 200 hamburgers, much to Tails' disgust). However, this doesn't seem to be much of a problem to Sonic since it can be implied that he can burn off the calories with his running.

In a story in the 11th issue of the Archie Sonic comic series, Sonic eats a bunch of chili dogs as a birthday present to himself, then has a food related nightmare where he is a chili dog. When Sonic wakes up, Sally Acorn and Tails give him a plate of chili dogs. Sonic at first refuses this present, but then eats them anyway.

In the Sonic the Hedgehog (Play-a-Sound Book), the plot is that Sonic is racing Robotnik in a scavenger hunt to win 6,000,000 Mobiums, which he says he will donate to charity. In the end, he wins the money and spends it on Chili Dogs instead.

In "Archie Sonic Mini-series Issue 0" Part II, Sonic mentions having a "Chili Dog break".

Game references
In the Japanese manual of Sonic Advance 3, it states that Sonic loves chili dogs.

During the end credits of Sonic Chronicles: The Dark Brotherhood, Sonic briefly mentions chili dogs.

In Sonic Unleashed, different hot dogs can be bought and won. Most stores even sell chili dogs, claiming that they're Sonic's favorite. Chip thinks they're too spicy for him, but does admit that they're good. In the instruction manual for the PlayStation 3 and Xbox 360 versions, it's mentioned that Sonic loves chili dogs. In Eggmanland, there is a green chili dog called the Egg Dog, which isn't appetizing to either character as Chip doesn't like them, and Sonic will only gain 1 experience point from it (this somehow strangely appiles to the Doggone Dog as well, but this could be due to the ingredients used in it and how bad Eggmanland's food is in general).

In the first cutscene of Sonic and the Black Knight, after Merlina the Sorceress summons Sonic, he falls from the sky with two chili dogs. After catching the chili dogs, he looks up to notice the Black Knight. He then eats one of his chili dogs, throws the other in the air. Then Sonic attacks and defeats the Knights of the Underworld, just before the chili dog falls on the ground. Minutes after trying to stop the Black Knight with the whirlwind Merlina created, Sonic's chili dog flew away to an unknown location. They can also be found as food item during the game, with the description calling them "Sonic's favorite".

In Sonic & Sega All-Stars Racing, under Sonic's profile, it says that he likes Chili Dogs.

In Sonic Generations, Sonic is given a chili dog as a birthday present (wrapped in a bow, no less). However, it is the first thing that is blown away when the Time Eater appears. In the ending, it flew back into his hands, and Sonic took a taste saying it's still warm.
