The TV episodes by Bardel Entertainment have a special style for drawing the bats. For instance, the have main-hair (At least that's what I call it). And, they have clawed hands (although still connected to their wings). If you live in North America (USA), you will not see the show air. You can order it on Netflix or watch it on YouTube. The TV series was produced in Canada.
