This is apparently called "Skywhale" and the title is accurate (although it's worth clarifying that "this year" refers to 2013, which is when the original Imgur post was made.)
A quote from the Wikipedia page:
Wings didn't make sense to Patricia; the creature was too big and the technical limitations of balloon design wouldn't allow them anyway. So she took a cue from the balloon itself, and imagined that the creature might somehow secrete a lighter than air gas. In the place of wings she imagined huge udders that might contain the gas, as well as a huge bulbous body. She imagined the creature with a slightly more human face, with a calm benign expression that would inspire empathy rather than fear. Her aim was to create a being that was massive and wondrous and that exists somewhere between the impossible and the unlikely.
