You were coming back to your hometown from an event that was lasting an entire week. The sun was shining brightly, and there wasn't a storm cloud in the sky at all.

You caught wind of the rumors about how there's sentient human/humanoid shaped balloons and inflatables that were introduced at the local balloon stores. Their sentience is quite natural, the personalities of each of the balloons and inflatables that are inflated, have varied personality types and traits that differentiate them.
