It seems to happen every year. Here is 2017's haul of lost and found items...
From the artist, Teskine:
So, Tomas is a California Leaf-Nosed Bat, which is very obviously a species native to California, especially SoCal. Named with a slight Latin flare, as much of SoCal shares, just as much as the species of bat itself which is also common to Mexico. I choose a native bat last-minute after rooting through multiple other species because they're a huge presence in our state, but often overlooked or taken for granted.
Tomas is a very energetic, outdoors-loving type into a large variety of sports. Surfing, hiking, skating, etc. You name it, he's game for it. This is of course because SoCal is almost eternally sunny, so you can enjoy being active year-round. He'd probably give Tamerlaine a run for her money... quite literally. I imagine them having a fairly competitive friendship.
The scene doesn't die down when the sun sets for Tomas, however. Like most residents of SoCal, he enjoys the opportunity for the night life. Whether it be clubbing or moonlit walks (or flits) he's always up to something interesting.
He'd also be able to be drawn with wings on his back alternatively for when it be needed.
