Mouse has had such problems. Deep down in his bones, he knows he is meant to be a traveler.. But he has failed at two attempts, trying to get to the moon, and he is about ready to call it quits. Then one day his friend Bird tells him there is plenty to see right here in his own country. Once again Mouse is ready to roll. Only problem? He has no idea where he wants to go or how to get there. Follow Mouse as he finally figures out a set-up for his many adventures to come. The good news is that Mouse has chosen a very unique National Park for his first park visit. In Joshua Tree, the trees are one of a kind. The flowers bloom thick and lush under certain conditions, in places it seems nothing should grow. And Mouse finds critters he had no idea existed on our earth.
