In these episodes of PBS's popular animated series, green-hued Bula leads a crew of alien cohorts as they zip through the Zulaverse, imparting lessons about science, astronomy, problem solving and friendship while fending off space villains. A many-eyed professor, a beloved shape-shifting space pet and the lovely pink pilot, Zeeter, are just a few of the zany characters who join Bula as he takes on the evil Dark Truder and his living toupee.
