I did try the flame with mine and as far as I know, they’re no gimmick for getting it in. It’s just carefully wiggling it in. I pulled the jaw down very slightly to help. I don’t recommend taking it in and out often as it’s likely to eventually chip paint.
I saw another review where they had to waggle the flame effect a bit to get it to go into the mouth properly but they were able to succeed, so it should go into your one but it's a tight fit for sure.
He looks dope but awfully pink vàto. I hope it’s your lights. Mines still boxed but I’m gonna bust him out. Disappointed about the effect mondo 😡. You just plug it in homie, magnet down. But I see your concern cuz it’s a tight fit.
