The Rock Tunnel will get you from Lavender Town to Route 10. It is neither complex nor large, so you shouldn't have trouble picking up all the items inside and finding your way out. Make sure you pick up TM 47, Steel Wing, when you first enter the tunnel.
From the bottom entrance (Lavender), go up and grab the Elixer on the left, then climb up the stairs onto the raised area and grab the TM 47 (Steel Wing). Return to dirt floor and head to the far right until you reach the wall, then go up and climb down the ladder to Floor 2 (lower-right).
- Second visit to Floor 1
From the ladder (center) head left, go up, and climb down the ladder in the northwest corner (upper-left).
- Final visit to Floor 1
From the ladder (upper-right) head left (a bit down, then left, then up, then left) to reach the exit. There is a hidden X Accuracy at the back of the dead end path lined by rocks (from the ladder go down, left, up a bit, then right to the end of the dead end).
From the northwest ladder, head straight down until you reach a dead end surrounded by rocks. Grab the hidden Max Potion along the west edge. Return up a bit, then to the right to a four/five way intersection (depending on how you look at it). Go down to get a PP UP. Return to the intersection and go right a bit, then head up and to the right to get a Revive. Return down to the intersection, head to the right, and climb up the ladder (center).
- Second visit to Floor 2
From the ladder (upper-right) head a bit to the right and then down. Half way down the map you will zigzag to the left and down. At the fork, take a left to get an Iron/Calcium. Return to the right and climb up the final ladder (lower-right).
|#115 Kangaskhan||#104 Cubone|
|Kangaskhan here, but it's the only place they show up in Gold, Silver, or Crystal. They haven't changed too much: High HP and good stats, but unexciting moves. It does have one new one, Reversal, which does damage equal to the amount of HP Kangaskhan has lost.||Cubone (and it's evolved form, Marowak), now have a third exclusive move: Bone Rush, a solid attack that strikes 2-5 times eash turn. It's Ground-type, too, so it's great against Fire, Electric, Poison, Rock, and even Steel Pokémon. Cubone also gets Bonemerang earlier, and can learn False Swipe (which is great for capturing wild Pokémon).|
