I do think Shugabush could take on an ethereal though, which including that one would be a potential increase of six ethereal monsters.. The breeding times could be a problem for bigger Ethereals, but maybe not. Yes, if they stayed at 10 hours for a 1-element, 42 hours for a 2-element, then I guess that implies something like 72 and 96 hours for 3- and 4-element Ethereals. Which would be madness. People would be deleting the game if they had a string of 72-hour failed attempts.

On the other hand, 1-element Ethereals are 36 hours on the Natural islands, and only 10 hours on the Ethereal Island. If we continued the trend in that direction, moving from "Ethereal Prime" to the hypothetical Plasma, Shadow, etc. islands, it wouldn't be unreasonable to see 4 hours for a 1-element Ethereal, 8 hours for a 2-element, and then 12 and 24 (or 16 and 32) for the 3- and 4- elements. That would make them pretty comparable to the Natural monsters.
