I've been so busy looking around this new world in edit town that I haven't yet started to play a normal game there.
If you like to find what is spawned on your own, please do not read the rest of this post. This is what I've found so far...
Community Lots:
Crystal Mine - Gem (epic), Meteor (huge)
Crater Lagoon - Deathfish
Hot Springs - Fish (Lake Common 1 & Ocean Common 2)
Memories of Appaloosa Plains (dome) - Beetles (Lightning Bugs), Butterflies (Monarchs & Med 2)
Memories of Riverview (dome) - Beetles (Lady Bugs), Butterflies (Kite & Moths)
Memories of Sunset Valley (dome) - Butterflies (Kite), Fish (Ocean Common 2)
Memories of Twinbrook (dome) - Beetles (Japanese), Butterflies (High 2 & Silver)
Memories of Hidden Springs (dome) - Beetles (All), Butterflies (High 1 & Zebra..this has beetle cube markings???)
I didn't see any seed spawners at all...no money tree if they didn't add them to this world
There are many established plants so picking and planting the fruits and vegetables will be easy enough.
I can't believe that I only found one gem spawner...there has to be more. Has anyone noticed whether or not they add spawners to areas that are not designated lots?
Off to see if there is a death flower to be found in Lunar Lakes
*Found by Twinmum: Special seed around Oasis Shoreline.
