Shaxon continued to perform a number of Harbin's illusions, including the "Blades of Opah II". There is also a tentacled creature that dwells within an oil pool seen in "Opah". Almost nothing is known of opah biology and ecology. Some fish have warm-blooded characteristics, such as the opah. The moonfish ("opah") is used for broiling, smoking, or making sashimi. The opah is not homeothermic (maintaining a stable internal temperature) like birds and mammals. Yap's mother, Opah, does not live with them but is often seen in their house.
