You were lucky enough to have stumbled across my brother's son, Mood Pebble.
Mood Pebble is not from the moon, but rather, it is a rock of the Caribbean that has the ability to exhibit different colors.
Luckily, the relationship between Mood Stone and Mood Pebble is much better than Vader and Skywalker in this scene.
Mood Stone is happy to be called a father, and it's just in time for Father's Day!
