On Fortnite, for season 2 of chapter 2, if you have the Battle Pass you will have access to different challenges that focus on the agents. These characters all have missions of their own. If you manage to complete at least 18 of the 20 proposed tasks, you will unlock a bonus challenge that will present you with a dilemma.
In fact, you will have access to two missions alternatives: one allowing you to unlock a Shadow variant for the skin, the other for the Ghost variant. For Skye, this challenge is to find Ollie of the Shadow or Ghost at Weeping Woods or Frenzy Farm. Ollie is her fantastic creature with whom she always moves.
The map
Depending on your choice, you will have to go either to Weeping Woods for the Shadow, or to Frenzy Farm for the Ghost.
Once there, Ollie is a real joker: he may be moving when you approach him : do not panic, follow him until he stops to pick him up. If he's going to take refuge in a haystack, break it to pick it up.
Once the beast in your pocket, you will automatically unlock the variant for Skye. Be careful though to choose well, because you can't go back on your choice!
