/tfg/ got me messing around with ye olde MP sunstreaker mold again and I discovered an extra step to transforming his legs (sorta).
The little window piece here that closes around the back of the leg can actually fit around more tightly than I initially though. At first it seemed like it was just kind of there and loose but if you push it with kind of a lot of force a little tab will click past the body of the leg and it'll lock in place. It also holds the inner leg panel in place with it and in general makes the legs close up more tightly with less gaps, which is neat.
Seems like a lot of owners and promo pictures missed or skipped this as well, which makes sense because it actually takes kind of a lot of force to do this the first few time, and considering the leg parts feel a little flimsy I don't blame em for leaving it.
