In the Perfectly Pixelated Puzzling Plaza, some people were setting off fireworks. Being the puzzling fellows that they are, they couldn't bear to just set off fireworks for the sheer enjoyment of it (who would want that?). So they decided to hide a message inside one of the fireworks.
And sure enough, as the particularly perplexing firework had been set off and the the sparks started to fall, some noticed a message that had been woven into that firework.
Perhaps, from this photo of the firework exploding, you can see the message too.
