E.T. the walrus, is one of the star attractions at the Point Defiance Zoo & Aquarium in Tacoma. E.T. arrived at Point Defiance after Prudhoe Bay oil workers in 1982 found him as a starving orphan pup and gave him his movie star name because of the resemblance. Raised at the zoo, he now weighs about 3,500 pounds and just marked his 30th birthday.
