This challenge is part of Fortnite Season 3 Week 2 Challenges and you'll have to collect or eat five fruits or vegetables from The Orchard. This location isn't mentioned on the map, but it's a rather important notable place, which can be found on the north side of Frenzy Farm.
Map
This type of challenge is rather recurrent in the game. We've had challenges like this before in the previous season. Here, the difference is that you can collect the food instead of eating it on the spot. In the Orchard, you'll find cabbage crops in the south of the place, and apple trees in the centre. Collecting or eating will help you progress in the challenge.
If you want to eat fruit but your HP bar is already full, build a five-storey ramp, jump up and down, and recover by devouring some food!
