* From the Old Man in the Lake of Rage: This is the most common and straightforward way to obtain a fishing rod. Once you have reached the Lake of Rage (after defeating the Elite Four), speak to the Old Man on the east side of the lake. He will give you the Old Rod.
* From the Department Store in Goldenrod City: After obtaining the Good Rod, you can purchase the Super Rod and Ultimate Rod from the Department Store in Goldenrod City. These rods allow you to catch more powerful Pokemon.
Here's a breakdown of the different rods and where to find them:
* Old Rod: Given by the Old Man at the Lake of Rage (after defeating the Elite Four).
* Good Rod: Found in the Goldenrod Department Store (after obtaining the Old Rod).
* Super Rod: Found in the Goldenrod Department Store (after obtaining the Good Rod).
* Ultimate Rod: Found in the Goldenrod Department Store (after obtaining the Super Rod).
Remember, each rod allows you to catch different types and levels of Pokemon. The Ultimate Rod is the most powerful rod and lets you catch the rarest and most powerful Pokemon in the game.
