Each monster in the game likes four or five things on each island. Below you can find tables for each island showing all the monsters available there, and all of the things that those monsters like. When a monster is close to a monster or a decoration it likes, it's Happiness will increase by 25%. A monster's Happiness caps at 100%, and cannot go higher. A monster's earnings increase when it's Happiness increases. If a monster likes 5 things, it is because the monster it likes is not on all the islands it is on, and needs another monster to fill that gap.
These likes only exist on the outer islands, due to the fact that monsters do not produce coins on the Continent.
The Decoration Storage Structure is also available on the Outer Islands, and unlike the first game a Unity Tree is not required for monsters to like decorations inside it. It is upgraded with coins and Crystals, starting with 10 decoration slots and going up to 15, 20, 25 and finally 30 decoration slots.
The update that introduces Likes also makes a second Workshop cost 12,000 coins instead of diamonds, and buy-only decorations are 10% cheaper than before.
Decorations added in this update are italicized.
