Mint Mango is a type of fruit found throughout Rainbow Island, and this makes this a very useful item for you to find. Unfortunately, Mint Mango is only available in one location until you bring it back to your base.
Where to find Mint Mango in Slime Rancher 2
After finding the Cotton gordo south of Rainbow Fields, you will need to travel to Starlight Strand, one of the two areas you can unlock in Slime Rancher 2. This area will require you to feed it vegetables to make it explode, giving you access to Starlight Strand, as well as other Slimes and items.
To get to Mint Mango's location, you will need your Jetpack, therefore, we suggest you concentrate on this first. Radiant Ore is available by defeating the Pink gordo on the north side of Rainbow Field, and this slime will devour anything.
Return to your base and build the Jetpack when you have enough Radiant Ore. They should be near Honey, Flutter, Puddle, and Hunter slime. We recommend finding at least one to bring back and grow in the garden as well.
