So, Ghostbur- loveable and friendly, is known for leaving small traces of Blue TM wherever he goes. Splotches of blue on walkways and buildings are the only traces of Ghostbur left, besides the memories people hold of him.
Now, Tommy isn't clumsy. A Big Man like him could never be, and when he accidentally trips on a step, Tommy catches himself. He continues running to find Tubbo because beeboy has been spending too much time with the lanky freak (affectionate?). But, Tommy doesn't realize the small bundle of blue he keeps around fell out. It lays on the Prime Path, forgotten.
And then a small floaty friend comes along, and picks it up.
The Allay cautiously opens the little pack, and blue dust spills out. The memories with the blue are plentiful. And the Allay takes a bite of them, and they're so rich with emotion. It looks around, and spots a patch of blue on a bench. More, it thinks, and drifts to collect the blue.
By the end of the day, there is no blue, and there is no more Ghostbur.
