Yes, that's really an Xenomorph from Ridley Scott's Alien attacking Futurama's Bender. And yes, it's really a sand sculpture. This past weekend, the town of Port Angeles, WA had a science-fiction-themed sand sculpture contest. Bender won, natch.
According to the Peninsula Daily News:
[Carl] Jara's sculpture depicts the creature from the "Alien" movies hunting the character Bender from the cartoon "Futurama," in keeping with the theme, "Legends of Science Fiction." The other winners are: Sue McGrew, second place for "Luke & Leia." McGrew, of Tacoma, will receive $1,250; and Damon Farmer, third place, for "Radio Visions." Farmer, of Versailles, Ky., will receive $950. Sculptor Jeff Strong received an honorable mention for "I. Asimov."
Also on display are "Planet of da Apes," by Fred Dobbs of Victoria; "I'll be Back," by H. Firat Uysal of Erdine, Turkey; and "The Three Laws," by Damon Langlois of Victoria.
