Nickelodeon has expanded its preschool programming slate with two brand-new animated series–“Digby Dragon” and “Trucktown.”

“Digby Dragon” is distributed by Aardman Animations and produced by Fizzy Productions. It centers on a young dragon named Digby who is learning to fly. Along with his best friends, Digby sets off on magical adventures in Applecross Wood. The series will premiere on Nick Jr. in the U.S., Jan. 23.

Meanwhile, “Trucktown” is produced by Corus Entertainment’s Nelvana and features a world populated by young trucks and centers on Flat Bed Jack and his friends Dump Truck Dan, Monster Truck Max and others as they roar, romp and rock their way through town. The show aims to illustrate that preschools can find solutions to any problem through gameplay and fun. The series is set to launch today, exclusively in the U.S., on Noggin, Nickelodeon’s video subscription service.

Additionally, Nickelodeon has also secured deals to air the second seasons of “Teletubbies,” “Miffy’s Adventures Big and Small” and “Hey Duggee” for the Nick Jr. channel.
