I got the key out of the green house but now the red gem is stuck inside. It is too large to get out of the same hole that I put the key through. I can’t find any way at all to get it outside while also being able to use the green gem to get me back to the central area of the map.
I feel like this might be a bug. If I brought the red stone inside when it was small, I could likely have thrown it out the back window but now I have no way of making it small again.
This one is a tricky one to get back out. Dunno if this is the method the developers had intended but this is what you have to do to get the red stone back outside.
