Birthday Letter
1: Today, Balloon Party will be hosting a party that will last a whole day, if not longer. 2: Don't worry, adults won't be interested in a spooky party with Bones Balloons decorated everywhere! She is the sole star of this balloon party attended only by children. 3: Balloon Party's wish is simple: that all the children suffering hardship could come to her party, and for each of them to get one of those adorable baby balloons of hers.
