The clock is mounted on a three-tiered tower above the arcade between the Wildlife Center and the Children's Zoo.[2] The clock contains representations of animals playing instruments, with two chimpanzees ringing a bell, and plays music every half hour, at 0 and 30 minutes past the hour, between 8 a.m. and 6 p.m. The clock's music is selected from one of 44 pre-recorded tracks.[3]
