It’s dolphin o’clock. How can one tell? The National Geographic Animal Sounds Wall Clock blares out an appropriate animal sound that corresponds to the animal of the hour. Starting with 12:00 lion and progressing to 11:00 wolf, this hanging timepiece features 12 different sounds (one on each hour) from the mammal kingdom, ranging from the endangered Bengal Tiger to the American Bison. Each clock is accompanied by an educational booklet that provides detailed information about each animal featured, and is designed to educate children or facilitate interaction between parent and child. The Animal Sounds Wall Clock was launched in 2005.
