Remove the Juvenile Antics is a part of the new Sakura Arborism World Quest in Genshin Impact that is now available for travelers to complete after the Inazuma update.
Ultimately, completing this quest is pretty straightforward to do, it's just that where to remove the "juvenile antics" is pretty tedious to figure out organically. Here's how to complete the Remove the Juvenile Antics step for the Sakura Arborism quest in Genshin Impact.
Remove the Juvenile Antics Genshin Impact: How to Complete the Step
After talking to Miyuki, investigating the Treasure Hoarder camp, interrogating the remaining Treasure Hoarders and reporting back to Miyuki, travelers will be tasked with removing five "juvenile antics" left on five Thunder Sakura Trees.
Ultimately, travelers need to go to all five of the Thunder Sakura Trees and retrieve foreign objects to surpass this task. Feel free to check out this video by WoW Quests for the five locations.
As hinted by Paimon, travelers will need to use their elemental sight when near each of the trees to see the sources of the lightning.
When using elemental sight, a few blue spots can be spotted on the ground near the trees. Stand on a blue spot to make lightning strike there and repeat the process until all the blue spots are done.
Eventually, flowers will start blooming on the nearby Thunder Sakura Tree and a foreign object will be able to be retrieved from it.
Travelers will receive 500 Adventure EXP, 40,000 Mora, 60 Primogems and four Hero's Wits as the Sakura Arborism quest reward.
