MILWAUKEE (AP) -- A playful polar bear pawing at a toy lost his balance and slipped into a moat at the Milwaukee County Zoo.
Zoo spokeswoman Laura Pedriani says a net caught Zero when he fell Monday so he wasn't hurt. Zoo workers cut the netting and the 19-year-old polar bear was walking around later in the day.
Pedriani says Zero might decide to climb out of the moat when he's hungry enough.
The polar bear is now closer to visitors but his only exit from the moat goes into his regular enclosure. A fence still separates visitors from the bear and the moat.
Zero fell into the same moat 15 years ago and stayed there for nine days.
