Pokemon Red and Blue Walkthrough

Route 2

Pokemon Type Red Blue
Caterpie Bug X
Weedle Bug/Poison X
Pidgey Normal/Flying X X
Rattata Normal X X

Route 2 is very short the first time around. All you need to do is go north until you see the route house. You may notice some small bushes along the east side of the route. You will be able to return here late to cut these down. Until then, go north to Viridian Forest.
