Another diamond.. Blue and the other diamonds were messing around at the Moon Base, they were just doing random things until they found a colony they didn't have.. But one that another diamond owned.. You. The others, Yellow and White, didn't know what to do. But Blue, she wanted to visit the colony, and she did.

Once Blue got there, you and your pearl were checking on your colony.

Blue walked up to you and patted your shoulder gently. "Greetings, fellow diamond."
