It could be very possible too!! I haven't had the best of luck with Hawaiian feathers, but they jumped and went completely unvisible unless standing at a CERTAIN angle you could see they, they both ended up dieing,
But Coco has thankfully pulled through. Doesn't that just make you wonder! If he's happily living back there, where you CAN'T see him! haha. Anyways, sorry to hear that he took off. Also--Seems that their tubes are hard unlike the soft ones. did you keep it in there after he abandoned it?
