If a land was animated by earthbend and would go to any zone other than the graveyard or exile, it will not be returned to the battlefield by the delayed triggered ability created by earthbend.

If the targeted land becomes an illegal target before the spell or ability that includes earthbend resolves, earthbend does nothing. If the spell or ability didn't have other targets, it won't resolve.

You may target a land that is already a creature, perhaps because of a previous earthbend ability. The land will get the +1/+1 counters, gain haste, and have its base power and toughness set to 0/0.

Whatever you do, don't eat the delicious cards.

Earthbend doesn't give the land you control a color. As most lands are colorless, in most cases the resulting land creature will also be colorless.

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.

"Earthbend N" means "Target land you control becomes a 0/0 land creature with haste in addition to its other types. Put N +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped under your control."

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

The land will retain any other types, subtypes, or supertypes it previously had. It will also retain any mana abilities it had as a result of those subtypes. For example, a Forest that's turned into a creature this way can still be tapped for {G}.

If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Tough Cookie (an Artifact Creature — Food Golem) to activate Bosco, Just a Bear's ability (an ability with "Sacrifice a Food" in its cost). You can't sacrifice a Food to pay multiple costs. For example, you can't sacrifice a Food token to activate its own ability and also to activate Bosco, Just a Bear's ability.
