Paul Bosch, the Oregon Zoo's new executive chef, may have worked for Elephants Delicatessen before, but he's never cooked for an actual elephant — until now. "I'm really looking forward to making Packy's 51st birthday cake," Bosch said. "It's always a little intimidating to cook for a celebrity, but we're trying some new things this year, and I think he's going to like it." Elephantastic, featuring Packy's 51st birthday party, takes place Sunday, April 14, from 10 a.m. to 3 p.m. and is free with zoo admission. Birthday cake for human party guests will be served at noon, courtesy of Lamb's Wilsonville Market. Packy receives his cake at 2 p.m., and visitors can join in singing a birthday song to the prestigious pachyderm as he chows down. For more information, visit oregonzoo.org/events.
