Organizers call it a "ghostly garden."
Some 5th graders at MLK Magnet School toiled in the soil to create this new attraction, learning about so-called scary plants, like the venus fly trap.
They're also getting a discount to this family-friendly event.
Some fifth-graders described the best parts of Boo at the Zoo.
"I think it's a pretty good thing to be out and good at the zoo," says Keith Bates. "It's just fun, you get to meet a lot of people like that."
Boo at the Zoo runs Oct. 16-21, and Oct. 26-31.
