Use the Swamp Route and you will find Slacking roaming the area. Using Scan, watch as Slacking begins to follow the path, moving away from the swamp. You will want to keep scanning the area until Slacking reaches a tree with a hole in its trunk.
Once you reach the tree, snap a photo as Slacking reaches in to grab some fruit from Pikipek‘s storage.
Once the Ledian are in the area, throw down some Fluffruit by the Ledian that’s walking around. As the Ledian picks up the fruit, snap a photo to complete the request.
