According to zoo officials, the Nigerian dwarf goats enjoyed playing with and eating the fall gourds and, Adele, a Nile hippo, also seemed to like her treat.

The pumpkin treats are part of the zoo’s enrichment items that work to mentally stimulate the animals. The zoo describes an enrichment item as something “they normally do not receive on a regular basis.”
