Before game version 1.16 the Decoration items in the game were organised by Themes like Classic, Mexican and Diner, making it easy to put things together that match a common style. With the update that changed to Categories like Ornaments, Lighting and Plants. This is good for browsing a type of content but if you aren’t very creative and find it hard to match all the content up, these pages will help. Below are all the items that match the original Diner Theme.
The Diner Theme is unlocked at Level 12
