Rose's Secret Armory

Rose's Training Cave was a cave that Lion brought Steven and Connie to that Rose used to train in.

About
The cave contains a raised platform which has a block in the middle that seems to be activated by Steven's gem. When activated, Steven can choose which equipment he wants to appear in the training via activating pressure points in his body, in one (and currently the only) instance, by Connie pinching and poking him. Equipment that appear include Laser Light Cannons, Spikey Chain Balls, a Giant penny, and an array of different types of Armor. They also accidentally unleash the episode's antagonist, the Robot Shooty Thing.
