First we need to know how much treasure pods contain decoration blueprints in each area. The Biomes in the game are the following.

• The Ranch
  
• The Dry Reef
  
• The Moss Blanket
  
• The Indigo Quarry
  
• The Ancient Ruins
  
• The Glass Dessert
  
• The Slime Sea
  
• The Wilds
  
• Nimble Valley
  
• The Slimeulation

Now we need to find out how many treasure pods are in these areas.

When I say themes I mean a group of decorations from the same area.
Just Remember you can do any theme anywhere this is just a helper.
So here is my Ranch that I play in.

• Main Ranch Area - Dry Reef Themed

• The Overgrowth Expansion - Moss Blanket Themed

• The Grotto Expansion - Indigo Quarry Themed

• The Docks Expansion - The Wilds Themed

• The Lab Expansion - Ancient Ruins Themed

• Viktors Workshop - Glass Desert Themed

And for Mochi's Manor and Ogden's Retreat just decorate their Ranches with their themes.

The Reason why I did not put Digi themed decorations anywhere is because there are only three decoration items and it does not look good if you place the same items everywhere.

This is the end of my guide thank you for reading.
And remember it isn't my ranch that I am decorating its yours that your are.

This is my first guide so hopefully the next one will be better.
