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

If Lita enters at the same time as one or more other creatures you control, Lita's ability will trigger for each of those other creatures.

If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Pizza Face (a Legendary Artifact Creature — Food Mutant) to activate Maraleaf Rider'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 Maraleaf Rider's ability.

If multiple other creatures you control enter simultaneously, you must still choose different modes for each instance of the triggered ability that's put onto the stack. If more than three other creatures you control enter simultaneously, that choice is made only for the first three.

If you can't legally choose a mode because all three have been chosen that turn, that instance of the ability is removed from the stack with no effect.

If you somehow control two or more Lita, Little Orphan Amphibians, track which modes have been chosen each turn for each one's ability separately.

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.

Whatever you do, don't eat the cards. (Also, don't make the pizzas pictured on the cards. You don't have the digestive system of a Ninja Turtle.)
