WOW you never saw gremlins 2? oh well, but it does infact connect to the first one. big corporation tears down the old chineese guys shop after he dies ( billy happens to work for them now drawing up landscapes of architectual designs or somethin like that) gizmo escapes before it collapses, two scientist find gizmo take him back to the lab which is also at the same company that billy works for( in the same building, go figure) billy goes down to the lab after hearing a mailman whistle gizmos song and asks him wear he heard it and he tells him what floor the lab is on and billy goes there finds gizmo takes him out gizmo gets wet and mogwai multiply, chaos ensues. whew, yea so they connect.
And it has got the Doctor from Voyager in it, only then he still had hair!
