The Zack Bots were trying to get the walruses. I liked the spaceship the Zack Bots rode in. Walruses have tusks that they use to search around the sand. They also use their whiskers. They are searching for clams in the sand. When they find them, they use their tusks to open the clam and then they eat it. A walrus can stay underwater for up to 40 minutes.
(I learned this from the Wild Krats)
