The Earth Day festival will take place in the amphitheater in front of the Reptile House, and includes five New Jersey artists.
Music with Molly, starring Molly Dorsman, will play at 11. Baze & his Silly Friends, who mix up nursery rhymes until a young audience member corrects him, will perform at 11:35 a.m.
Miss Nina, a YouTube star well known for her “Brown Bear Rap” based on the Eric Carle/Bill Martin Jr. book, will play at 12:10 and 2:10 p.m. The Fuzzy Lemons, who combine rock, funk and blues, will play at 12:45.
Jason Didner and the Jungle Gym Jam, whose song “Five Sea Lions” was inspired by the zoo, and whose musical style has its origins in the Jersey Shore sounds of Bruce Springsteen and Southside Johnny, will play at 1:20 p.m. Their stage show uses puppets, freeze dancing and hand gestures to illustrate the ideas in their songs.
