Something odd in episode 12. Alto's cockpit in battroid mode still has the bit from the rear of the canopy behind the pilot in it, while in previous shots of the cockpit (such as Ozma's from episode 2 and 3) it's clearly not there (because if you think about it, it's not supposed to be.
Alto's cockpit in episode 12.
Ozma's cockpit in episde 2.
I also recall something similar with Michel's cockpit in one episode, where he's in battroid mode, and we still see the front bit that divides the forward part of the canopy (again despite being in battroid mode).
