Tank

In the Lost World of the Dinosaurs, something strange is happening: giant plants are withering, and lava rivers are freezing. Buck realizes that the balance of the "Heart of the World"—a giant geothermal crystal that warms the underground jungle—has been disrupted. The crystal has been stolen, and the trail leads to an uncharted, deep part of the underground kingdom, where even the Tyrannosaurs fear to tread. Worse yet, Rudy (Buck's sworn enemy, the Baryonyx) has also disappeared, and without a rival, the weasel is rapidly losing his mind from boredom. To keep it together, he follows the road with Manny, Sid, and Diego. Along the way, they find two opossums named Crash and Eddie *.

Buck saw a white weasel, and everyone decided to adopt her. She also loved adventure, but she was very cautious.*

Buck began to fall in love with the weasel, but he didn't show it to anyone.

Tank. Not a tank, but a tank.
