In the first season of this hit animated show, 8-year-old Diego Marquez (of "Dora the Explorer" fame) travels to Antarctica, the rain forest and other exotic locales to rescue wild animals in peril, including a beached humpback whale. While Diego and his pal Baby Jaguar help penguins, an anaconda and other critters, they also teach preschool-aged viewers problem-solving skills and Spanish vocabulary words.
