Jar Dwellers SOS Two siblings, Sophie and David, discover and release three amazing creatures from special science jars hand made by famous naturalist Albert Derwent. Ooble, Crunch and Barka are not ready for repatriation so Sophie, with the help of Derwent's Big Book, introduces them to her "Survival of Species" program. They learn to avoid Professor Van Riceberger, his Jar Trackers and his assistant Chang. The creatures have no plans to return home. They're out and there is no going back.
