I also posted this in maintenance as I was not sure what category this fit best: New to the group, thank you for the add! Forgive my lack of experience, but I was wondering if there was a solution to the air pressure/pushing effect when entering either canal. A lot of toys have an additional hole for air to exit, however the higher end dolls don't seem to have said hole. I have experienced an intense pushing effect when the canal is completely full and sometimes just entering. Also if any air escapes or slips past there is a suction effect. Are there any modifications recommended to alleviate this pressure build up? Thank you very much in advance.
