The last confrontation with Frieza is approaching, but before it does, why not help one of his soldiers during a new Dragon Ball Z Kakarot sub story? After a good fight, Chef Malone will ask you to go pick some Namek fruit for him.
Rogue Chef Malone
As mentioned above, the quest begins with a fight against Malone. You're only going to take a bite out of it since it's just another "pretext" fight. Once the storm has passed, he will ask you to go and pick some fruits scattered in the area.
Yuckermelon
The circle closest to you: go directly under the arch to get the fruit.
Rollonut
Head to the circle north of your position and activate the ki to search the water. You should see the object shine near the beach.
Ajisa Orange
Last research circle, the southernmost: the fruit is placed between a few trees, north-east of the circle.
You now have everything you need, so you can return to Malone, who will give you your reward. This quest does not give any soul emblem.
