Ghosts, goblins and kids frolic at Oakland’s ‘Boo at the Zoo’ event

“Look! It’s a unicorn!” Justin Ochoa, 10, decked out in a Super Mario Brothers Luigi costume, called triumphantly to his parents during a scavenger hunt at the Oakland Zoo on Saturday.

Dubbed “Boo at the Zoo,” the wildlife park’s annual Halloween event was adapted this year for social distancing, but the Tracy resident and his fellow visitors seemed to enjoy it just as much.
