Nickelodeon will debut its new animated literacy series for preschoolers, “Wallykazam!,” on air Feb. 3, but the show will premiere first a week earlier on iTunes.

“Wallykazam!” follows the adventures of a troll named Wally who uses words to transform the world around him. 

"‘Wallykazam!’ offers a new approach to literacy by weaving it into a comedy-driven story with funny characters and adventures that will keep preschoolers laughing and engaged," says Teri Weiss, executive vice president, Nickelodeon Preschool. "The series furthers Nickelodeon's commitment to producing high-quality, curriculum rich content that helps prepare young children for the important adventure of starting school."
