Food nipple

The Food Nipple is an invention of the Covenant for feeding Unggoy.

Background
The Unggoy, having such a lowly place in Covenant society as cannon fodder and subservient thralls, lead an existence of servitude and feeding at these nipples is one of their very few real pleasures. Many Grunts do not enjoy feeding off of Food Nipples: however, they seem to just put up with it because it is their main source of nutrition. They appear as a long tube with a nipple at one end to consume from. They contain a blue, bubbling paste that the Grunts find unappetizing but nutritious. McKay describes the smell as "old socks wrapped in rotting cheese".

They are described as free standing food-dispensers, with long tubes and receptacles that end in a nipple the Grunts use to distribute the food into their gullet.

Trivia

 * The Thirsty Grunt in Halo: Combat Evolved says "Good thing the food nipple's waiting for me back up on the star ship, 'cause man! I've worked up a great big Grunty Thirst!"
 * The Grunt who mentions Flipyap also mentions that they "went to Nipple Academy" together.
 * Also, in Halo 3, if IWHBYD is turned on, a Grunt may say: "He flees! Thank the nipple...".
 * In Halo 2 on the level The Oracle (Level), after the grunt says he has a bad feeling another grunt says " You had a bad feeling about the nipple this morning."
