Laser tag is a sport of action, which is what Rainbow Dash is all about. It makes sense that if she and Fluttershy were in a relationship, she'd take her to a laser tag arena as something they could try doing together. It's certainly a better choice then paintball since Fluttershy bruises like a soft summer peach.
Aw. A nice take on Humanshy. That hair looks lovely, and the face is shaped in a way that fits her. This is totally her, indeed. Bonus points for that Chibidash head. That hair is, once again, gorgeous and this time, also funny, in a good way. Well done.
