I seem to be stuck on Android. I'm at the part where the twins have asked who has bigger boob's. I ordered the ruler and the hint says meet them at night. But no matter what time I find them there is never any option except nevermind. Been through several days of this now.......

You have to find them in their room or the bath I think

yeah they are in the bath at night but the only option I get is never mind lol. I have found them everywhere at all times but never an option for anything else....

NVM figured it out. You can't teleport to them you have to walk into their room even though they're in the bathroom lol. And nice touch on the ruler BTW!
