I just bought a deluxe ROTF Sideswipe figure, and while I enjoy the awesomeness of the toy and the slickness of the car mode, it seems that my Sideswipe is currently locked in robot mode, and I'm unable to get him back into the car mode.
The problem is that I can't un-hook the chest area of the robot. When I transformed him from the car mode, I fold it to connect the upper and the lower part of the chest (step 5 in the instructions), and securely locked the little hook with the hole together - and now I can't separate 'em off.
Do I just pull it really, really hard? Coz everytime I want to do it, it feels so secure and tight, I afraid it might snap and break if I continue trying. Can anyone tell me how to do it properly? Thanks in advance.
