Poachers are stealing the animals from a newly repopulated island. As they try to get away with their live cargo they also load Ben onto the truck, but he is spotted by Mark. The poachers are apprehended after a chase involving Tom, Boomhauer on his 'buggy', and the sheriff.

Feeling neglected by his hard-working father, Mark's friend Jamie runs away from home. He hides in a shipwreck but it is in danger of being washed out to sea in a fierce storm. Based on a hunch, Mark leads everybody to the boat and they rescue Jamie.
