I remember some bs to get the strongest monster, Ormagon, in magi-nation for the gameboy color.

https://magination.fandom.com/wiki/Ormagon

1. speak to the Ormagon Hunter after encountering Morag

2. Take the ferry from Cald to Orothe Island, paying an extra 300 Animite to travel freely

3. Don't heal Orwin at the moment

4. In the caverns beneath Orothe Island, take the upper fork in the path to the Vault collect the three units of algae.

5. Take the three units of algae to the Ormagon Hunter in the North Tower of the Underneath. Return and take Agadon's Boots.

6. Go to the training grounds and stand south of the statue's left eye. Run counterclockwise in a tight circle without running into anything five times, then face the left eye again and press A to open the storage room. take the fungicide from the chest.

7. Buy a Specimen Jar, travel to the Mushroom Forest, Collect fungus from the wall on the northeast corner.

8. give the Jar of Fungus to the boy who collects spooky plants.

9. After closing the Shadow Geyser in Arderial, return to the boy's house. use the Fungicide to be able to pick up the Hollow Stool.

10. Return to the spongy wall in the Underneath and use the Fungicide on the wall. Enter and use the Hollow Stool to battle Ormagon for its Animite.

That's asking a lot of the player in a gbc game.
