Watch The Wild Thornberrys Online - Full Episodes

Eliza is determined to play vet to some penguins, and misinterprets a penguins request for food, bringing the bird to a base for observation.

Grandma Sophie and Grandpa Frank surprise the Thornberrys with a visit to celebrate their fiftieth anniversary, but when Eliza and Grandpa want to climb Mt. Fuji, everyone thinks they are respectively too young and too old. The two sneak away in the night but soon find that the climb is harder than expected, and Eliza learns that her grandpa is not as able as he used to be. When Grandpa helps mend a wounded bear, however, his spirit is renewed, and they make the climb.

When Debbie's e-mail boyfriend, Sven, breaks up with her, Eliza tries to cheer her up by getting a reluctant Debbie to swim with dolphins. Debbie takes to the water and soon the kids and Darwin are out to sea in a small boat, where they encounter a deadly tiger shark.

The Thornberrys run out of gas and meet a family who could be their Aussie doubles. Eliza hits it off with Bethany, but is awkward and overprotective when she realizes she's in a wheelchair. While out exploring together (and trying to avoid the legendary "mamu" creature), Eliza continually shelters Bethany from potential danger until Bethany tells Eliza she doesn't need to be protected.
