it allows you enter old unused creature stage editor. I found in my spore files this modification. Spore: Creature Stage Level Editor Mapping Tool 18 comments.
The Biggest Spore Mod 2014 Adds massive amounts of Upgrades and content.The Mod adds feature that Spore should have put in the game on release. No harm can come from trying, as long as you've made a backup. These are made for Galactic Adventures with patch 1.5.1, but some of them may still work on Core Spore.
Also I have seen a mod with some parts similar to Grox (some cannons n stuff) if you know the name please tell me. The models created by modders were invisible and soundless. Putting things like turrets, sporebucks, or whatever on the creatures worked.
