I'd reccomend taking the head off, taking the orange side panels off the head (just grab everything orange). Take off the wings and the obvious back and front panels and that should give you nice box with feet to start with.
There are a couple of wonky things in the file, one wing has 3 1x2 plates in and the other only has 2, and somewhere in the face area one side has a plate while the other side has a tile and a gap but it all goes together well in the end and is super cute so I appreciate you releasing the file, Tron.
