Dolgat in Red, Blue, and Yellow

Dolgat is only caught in Red, Blue, and Yellow through a complicated glitch. It is near impossible to do it without some form of cheating device. Dolgat flees after the first turn, so MasterBalls are necessary. To get Dolgat, these are the steps that you must take:

1. Fly to the Safari Zone.

2. Catch a Pinser with exactly 137 steps left.

3. Fly to Pallet Town.

4. Talk to Professor Oak 506 times.

5. Head to the grass North of Pallet Town.

6. You will be instantly battled by a Pokemon called DOLGAT. Throw your MasterBall.

Then, you will have your own Dolgat.
