It's that spooky time of year. And it seems that it's not just humans who are having Halloween fun. Here's Kito the chimp munching on a treat at America's Oklahoma City Zoo.
Another chimp - this time at the Miami Metrozoo in America - tries a Halloween snack. It's a coconut disguised as a pumpkin. Cunning!
Flower the skunk at the UK's Chessington World Of Adventures is fascinated by this pumpkin. Maybe she thinks it's a new toy?!
Here's a pumpkin with a difference. It's filled with tasty snacks for this silvery marmoset at London Zoo in the UK.
Also at London Zoo, a pumpkin has caught this sloth's attention. Remember, YOU can send us your Halloween pictures. See the links at the side of this page for more info.
