Whether it is by bumping foreheads, twining trunks, rubbing noses, or simply waving, everyone and everything says hello in different ways. Offering a low growl deep in their throats, “that’s how two lions say hello. Mmmmmm. HELLO.” Chimpanzees may “say hello with a hug or a kiss. HELLO. HELLO.” Exploring some other well-known animals, such as zebra, elephants, and penguins, this informative investigation of greetings will have young readers bowing, jumping, and even flapping their imaginary wings to offer a greeting to one another. One final two-page spread features a little boy offering a greeting of his own as the animals look on. Simple, yet eye-catching illustrations rendered in oil paint on textured paper are presented as double-page paintings. The texture adds reality to the fur and feathers depicted in the close-ups of animals demonstrating their greeting behavior. Informative, with play-along potential. (Picture book. 2-5)
