Well the reason I popped the head off the new qee is because it doesn't come with the keychain already attached to the head like the tokidoki qee does... It comes on a little stand with the keychain on the side (like an optional attachment). I didn't want to just just steal the toki's keychain attachment because I want each qee to have its own chain so I'm not always popping off heads to get them loose... All I have to do to switch them out is change the chain. (I'm afraid that if I pop off the head more than the one time to put on the chain that it might eventually get loose)
