Despite their sunny looks and reputation, geckos are nocturnal carnivores just like hyenas and vampires. Finger Geckos can be used 24 hours a day, but don't be surprised if they seem more active at night. These 2" (5 cm) tall, soft vinyl gecko finger puppets come in four different shades. These scare bugs and nervous adults. 48 count. Bulk. Illustrated display box.
