The Israeli-born, English-reared African elephant has settled in and is inviting everyone for a visit Saturday to learn about his new American life.

These days, Osh loves to play just like any other 10-year-old, said elephant manager Jeff Kinzley.

"Wrestling is his favorite game," Kinzley said. "He loves to wrestle with Donna (a 25-year-old elephant), and they play very rough -- smacking heads and tusks, grabbing trunks and twirling and twisting them."

Osh also likes to make mud holes, digging with his head, feet, and body to create a crater twice as large as himself, Kinzley said.

The zoo expects between 2,000 and 3,000 people Saturday and will open an hour early with a 9 a.m. breakfast.

Since his arrival, Osh has grown six inches to 8 feet 6 inches tall at his shoulders. He even lost two upper baby teeth. He weighed 5,650 pounds when he arrived. Zoo officials invite visitors to guess his current weight in a contest at Saturday's celebration.

The zoo will also feature a film documenting Osh's 54-hour trek to Oakland by ferry, plane and trucks from Howletts Wild Animal Park.

Osh's arrival came after a three-year search to replace another bull named Smokey, who died of chronic wasting disease in 2001.

Osh joined the zoo's three cows - Lisa, 27, M'Dundamella, 35, and Donna - and rejuvenated its elephant program, said zoo spokesperson Michele Strider.

According to the American Zoo and Aquarium Association, 83 accredited U.S. zoos have 295 elephants.

Osh may begin to mate when he reaches adolescence in three to five years depending on his size, Strider said.

Until then, like any 10-year-old, Osh savors watermelons, picks out mushrooms from his meals, gets his face, ears, and toes washed daily, and goes to bed by 10 p.m.
