Lettuce

Lettuce is a minor character who appeared in Annoying Orange: Tough Enough as a flashback and the Annoying Orange episode Kitchen Carnage. She was warned by Orange and Pear to leave the kitchen due to the recent slaughters that killed Strawberry and two kiwis, but she realized too late what was going on and was knifed.

Trivia

 * Lettuce is the fourth female character to be knifed.
 * She was sliced clean through with one cut, but not a "saw" cut like Cabbage because cabbage is much thicker than lettuce.
 * She's also the first lettuce in the Annoying Orange series.
