Mexican Cow is a medium-sized Cow who likes tacos and sombreros. He first appears in Angry Birds: Out of Darkness. He dances with his sombrero sometimes. His favorite song is La Cucaracha like Mexican Pig.
He will dance around and throw tacos at the screen in an attempt to blind the player. The tacos will disappear after a bit, but it still can be a very big distraction. Use the fan power-up, which is the only free power-up, and pop the Mexican Cow.
Mexican Cow likes to dance and run at people to try to sell tacos. He wanted to do this to the Birds, but King Cow made him fight them instead.
