Diego, giving a tour of his Rescue Center to his new young friends Rosita and Martín . All of a sudden, they hear a distress call. A mommy duck's baby is missing--only to be discovered in the same pond as a fierce crocodile. With typical ingenuity, Diego and his sister Alicia save the frightened little duck with a lasso and return it to its concerned mother. Rosita and Martín are in awe of this rescue and demand that Diego tell them more about his encounters with his "fiercest" animals. In order to do so, they must enter Diego's Adventure Cave, which can only be opened with the secret password: Fierce Animals or Animales Feroces. Inside Diego shows his young friends videos of some of his greatest and most exciting adventures with wild animals.Diego recalls his encounters with gorillas, a blue-ringed octopus, grizzly bears, hippos, lions, elephants, and finally a full-size jaguar. In each mini story, Diego, with help from Alicia, Rescue Pack, Mami, and Papi, sees how fierce animals protect their babies and helping them with situations (such as a gorilla getting caught in a trap, a poisonous blue-ringed octopus whose home has been destoyed, grizzly bears looking for food, and a hippo getting stuck in quick sand).
Fierce Animal Rescues
- In central Africa, Diego helps a gorilla get out of a trap and acts like a fierce gorilla to scare away elephants.
- In the ocean in Australia, Diego and Alicia scare away sharks with Blue-Ringed Octopus and help rebuild his home.
- In Alaska, Diego and Mami save a baby grizzly bear and help his family look for fish in the river after their long hibernation.
- In the grasslands of Africa, Papi accidentally drives the rescue rover in quick sand and can't drive it out, leading Diego into asking a nearby hippo to charge at the rover and knock it out of the quick sand, which leaves a big dent in the rover.
