It is identical to all other ball gifts, apart from its color scheme, and has multiple characteristics that make it unique compared to the other gifts that have been released. The ribbon that surrounds this gift is a gradient aqua that darkens as it moves down the gift. Despite having "blue" in its name, it doesn't actually have any blue (excluding other colors similar to blue), as the colors are either aqua, cyan, and other shades. The model for this gift and ball was made by Seedonat0r.
One of the most distinctive features of this gift is its size. The Happy Blue Gift of Fun is a bit smaller than the Wobbly gift series and much smaller in comparison to the Jingly Gift of Jingles and the BIG GIFT. However, this gift still remains about four times as large as the Acceptable Gift from Bob in volume.
