Leonel exited his Dream World and smiled, taking the little Metal Spirit into his hands and playing with it again. 

"This'll be our first project together, Tolly. Are you excited?"

Tolly split into numerous balls of silver, jumping around Leonel's hands like little globules of mercury. The little guy didn't need to speak for Leonel to know that it was excited. 

Recently, Leonel had been feeding it a lot of metals. Earth might have not been a Fourth Dimensional world just yet, and as such, was lacking in high quality minerals that came with this evolution. But, they as a people had squeezed everything they could out of the materials they did have, creating alloys that this little Metal Spirit loved to eat at its current stage of evolution.

Tolly's favorite snack was an alloy of platinum and iridium. Using it, the little guy had already reached the Fifth Black Tier.
