"Spies feared on Stairs. Double vigilance. Patrol to head of Stairs."
—Shagrat's orders

Cirith Ungol Patrol

{1}, {T}, Sacrifice another creature: Draw a card, then create a Food token. (It's an artifact with "{2}, {T}, Sacrifice this artifact: You gain 3 life.")

The Lord of the Rings: Tales of Middle-earth

Do not eat the delicious cards. No, not even for second breakfast.

Food is an artifact type. Even though it appears on some creatures in other sets, it's never a creature type.

If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Lembas, an artifact card with the Food subtype, to activate the last ability of Bill the Pony.

Some spells and abilities that create Food tokens may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't create any Food tokens.

You can't sacrifice a Food token to pay multiple costs. For example, you can't sacrifice a Food token to activate its own ability and also to activate the last ability of Bill the Pony.
