Derpy in the rain
Complete with bubbles! I was originally going to just do the one bubble around Derpy and leave it at that. But as I was making it, I thought it might be a good idea to not only put bubbles traveling upward and getting smaller in size, but to also make the bubbles look like her cutie mark. (It's not perfect, but meh)
