I heard so much about this rumor back when Red and Blue first came out. Use Surf from the S.S. Anne's dock to get a truck. "Move it with Strength to find Mew!" Then there was "Take the car keys from the Game Corner, use them to move the truck!"
I, however never actually saw this much talked about truck. Does anyone have a screenshot of it? I've seen it in LeafGreen but I'd like to see how it was rendered in Red and Blue.
Obviously I know all of the rumor were disproven but this still always left me curious as to why it would be there at all - there was almost no background scenery objects back then.
