Thirty times in this incredibly annoying ten-hour video, a speech bubble with a letter appears over the guitar-playing Spongmonkey. These letters spell TIMESTAMPS AS MINOR PLANET NUMBERS. If you remove the colons of the video's timestamp at that moment, you get the numerical ID of a minor planet. What that Spongmonkey actually says on each occasion, however, is a number from one to nine. (You didn't mute the video, did you???) This tells you the letter to take from each minor planet's name.
