The stuff works but for some reason the metal plates inside that help transmit the electricity from the bottom cap to through toy aren't connecting with another part on the toy even though i screwed on the cap perfectly
You can contact CS by phone in the morning. Or if you prefer, file a ticket on it. EF's CS department is very nice and helpful.
I'm so sorry this has happened.
I've had the toy at least a month or so and I wouldn't really be comfortable sending it back because if anything happens and the package opens or something and someone sees it, it would be extremely embarassing.
