Tibanna gas was excreted by beldons, huge gas-filled creatures. The gas was a by-product of the vapors consumed by beldons. Tibanna was extracted from Bespin's atmosphere as atmospheric gases rose on updrafts through Cloud City's unipod. The gas was then processed and packed in carbonite for transport off-planet. The spin-sealing process was prohibitively expensive except on Bespin, where it occurred naturally. Non-spin-sealed tibanna gas was used as hyperdrive coolant. Gas giants with significant amounts of tibanna were known to possess a layer called tibanisphere.
