As one of Groot's awakening challenges, you will have to take on the role of Groot in front of a Friendship Monument in the game. The Friendship Monument is actually the Pipe Man and the Hay Man standing by. give each other a high five, so it's nice to see that friendship is alive and well in Fortnite.
The first thing to do is to equip the Groot skin which you can unlock at level 38 of the Battle Pass. You will need to reach level 46 before you can complete this challenge, so you will definitely have the skin. Go to the point shown on the map below and perform an emoticon.
You don't have to do anything else, a simple emote will do the job and unlock the special Rocket Racoon emote that Groot can get. The emote is, frankly, amazing, as Rocket Racoon will be flying around Groot, looking for enemies and threats. It doesn't actually do anything, but it's a really nice touch to the skin.
All of the heroes in the game this season have similar awakening challenges that will unlock a built-in emote that performs some special functions. It's a really nice touch and adds a lot of character to the new skins for the Marvel and Fortnite collaboration throughout the season. You will normally have access to Awakening Challenges for every 5-6 Batlte Pass level skin after you unlock them.
And that's not all, there are also secret Silver, Gold, and Holo Foil skins that you can unlock after completing the Main Battle Pass. As such, there is plenty for players to do before the season ends on November 30.
