Another Lost Toy

The brief
Oh no! Where is it? After a loooooooong throw and some weird rustling noises, Nala went for a long search, but came back without her toy and a sad look on her face. Where could it be? Could you help her find it?
Normal Sudoku rules apply: Place the digits 1-9 in every row, column and box exactly once each.
Every digit that appears in a circle must also appear in at least one of its 4 surrounding cells.
If an arrow is present in a cell, the digit in the cell the arrow comes from appears in the grid in the direction of the arrow at a distance of N cells, where N is the digit in the arrow's cell. (Not all arrows are necessarily given - there is not negative constraint.)
Example: If R3C4 had an arrow pointing to the left and was a 3, and the digit below that arrow in R4C4 was a 5, then another 5 would be placed in R3C1.
Additionally the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
