Core Memory Orbs

Core Memory Orbs are are vitally important objects from the upcoming Pixar film Inside Out. These special kinds of Memory Orbs contain a very special memory (like an accomplishment or behavior trait), and it activates/creates an island that serves as the basis of that person's personality and interest. All the Core Memories are yellow in color, meanning that Joy is the sole creator of these special memories.

When Joy and Sadness get vacuumed out of Headquarters, they tooks the Core Memories along with them. Without the presence of the Core Memories, the islands that build up Riley's personality began to shut down and eventually break down and fall into Riley's Subconscious.
