The Phoenix Zoo welcomed some new critters over the weekend.

Three reticulated Gila monsters hatched from their eggs, according to a post on the zoo's Facebook page Monday.

The post said that the new babies are the first in several years at the zoo.

They were incubated for 123 days, and all babies are healthy, the post said.

The zoo plans to display at least one of the Gila monsters at its Small Wonders exhibit along the Arizona Trail soon.
