Seeing: An ordinary game of "hide and seek" takes a not-so-ordinary turn when Baby Bop claims that an elephant is hiding in the park! Barney and Riff are happy to play along, but BJ thinks that his sister may be "seeing things". Fortunately, Barney takes this opportunity to help the young dinos learn about their sense of sight while having tons of fun! Hearing: BJ and Riff engage in a friendly contest to see which of them can find (or make) the loudest sound in the park. The playful competition continues to escalate...and along the way, the sounds of animals, musical instruments, and even fire engines are introduced.
