It seems there is something inside you waiting to be released. In
fairytales the frog king is very important, often it's a helping
spirit. The way in which the creatures take shelter probably means
that they shall not be exposed to daylight consciousness, at least not
too much. So you don't need to know exactly what it is, in time it
will show. The release of the spirit in a bottle is a common motif.
Often the spirit, or the frog king, is very grateful and will help its
rescuer in the future. It's renimiscent of a birth. It's a lucky
symbol, I think. The small lobsters, however, could perhaps point at
trouble, but I'm not at all certain what they mean. Maybe they are the
frog king's helpers.
