I suggest you get a rod (Old rod, good rod, super rod) or find HM03 (Surf).
In Pokemon Crystal you can find Dratini in Dragon's Den and Route 45. To find and catch Dratini you will need to use the Good Rod or Super Rod.
Yes
There is a fisher in Kanto near where you get off the boat
in the crystal maze wich is around the bend from the saveing point.
to get a super rod u have to go to the south of lavender city and talk to the fishing guru and he will give u a super rod.with it u can catch water Pokemon at lv 40.
if you have a super rod go to lake veriti if you have a super rod go to lake veriti
you can find the old rod on route 32 or you can find the good rod in olivine city
In Pokemon Crystal, the Hyper Rod can be obtained by talking to the fisherman on Route 32, near the Union Cave entrance. The fisherman will give you the Hyper Rod as a reward for showing him a Red Gyarados, which can be found at the Lake of Rage. The Hyper Rod is a special fishing rod that allows you to catch higher-level Pokemon compared to the Good Rod or Old Rod.
You can find a good rod on route 209 or you can find a super rod in the Fight Area.
Go to Lavender town, then take the road to the south, and keep walkin. When you see a little house, go in. There will be man who gives you the Super Rod. This is on Route 12.
Ultra rod is not available in Leaf Green. The super rod is the best rod in the game.
