Actually...the reason that the LBT series has been going on for much longer then it should is not the one you’d expect. It turns out, that each story that plays out in the movies is all from different parallel universes. Everything from those universes are the same as the original, but the type of adventure that the Gang goes into is different each time. But don’t get me wrong, time is passing by, but at an decelerated rate mind you. If we combine these adventures into a real time line, each of them occurs within a gap of two weeks, which is why you never see any age difference in any of the characters.
Berry Valley is the best place to inhabit.
