Any tips on how to get the batteries out of this RID 2015 Prime?

Already had a go at it recently, removed the screw on the back, which makes his wing come off, then there is no panel to open for batteriers. THe next back screws will basically make the toy fall apart, leaving me to wonder if I'm missing something, as none of my other battery ones require total dis-assembly of a toy to remove the batteries. Any help much appreciated as I'd rather not break it in the process of just removing the batteries.
