NAPLES, Fla. --- Lions, tigers and bears ... oh my.
Things got a little spooky earlier Saturday at the Naples Zoo, for their annual "Boo at the Zoo" celebration.

The family friendly event encouraged kids, ages 12 and under, to come out in costume.
Prizes were given out to the best look, and kids enjoyed Halloween themed exhibits, like the big cats "carving" their pumpkins.

"Enrichment items for the animals to tear into. We put a lot of food rewards in there and the animals get excited ... kids watch it, it's a good time and keepers come out and explain what they are doing," said presenter Mark Mullen.

Mullen says the event continues to get bigger and better every year, and that the zoo is happy to hand out candy to all those trick and treaters, a few weeks before the official holiday.
