"If Ethereal Island seems otherworldly to you, you're spot on. Located in a pocket dimension of the multiverse, it is home to monsters unlike any that have been seen or heard before. Oozing with mysterious substances and orbited by objects of ominous origin, you won't be able to resist the sublime wonder of its song!"
About
Ethereal Island is available at level 4 for free, after purchasing Cold Island.
Ethereal Island can hold the Ethereal Monsters from other islands after being Teleported, once fed to level 15. Teleporting will reset their levels back to one, and turn the monsters into eggs again. Teleportation is currently impossible to reverse, so the monsters will stay permanently on Ethereal Island.
Ethereal Island does not use coins 
for currency, instead it uses its own currency called shards 
.
This is the only island that allows Ethereal Monsters to breed.

Castle Upgrades

Upgrade the Castle to unlock more beds. The Ethereal Island castle and its upgrades hold a great deal more beds to account for the greater number of beds occupied by a single Ethereal Monster.
Strategy
While the song of the island is crucial, users may also want to use some of these numbers to help with planning which monsters to feed first and make 100% happy first, as well as plan frequency of shard collection. The numbers below are as follows:
| Rate | Rate of income per bed at level 15 and at 100% happy |
| Max | Maximum income per bed at level 15 |
| Time | Time to maximum income at level 15 and at 100% happy |
It should be noted that Rate is half for 0% happy, and Time is doubled for 0% happy. Rate is also shards per hour instead of per minute.
| Monster | Rate | Max | Time |

| Ghazt | 48 | 288 | 0:06:00 hours |
