I'm having trouble. Firstly, I've never owned a Blaster toy before. As soon as I saw this dinky version of him, I had to have him. Trouble is, I can't get his handle to unhook so I can get him in robot form. I'm terrified of breaking him because he's so tiny (and I heard someone else at BotCon bought one and almost broke it - there's stress marks on his), but the handle just won't unhook. Can someone help me ...?
