You only need to use three scatter plots in your view to access the free spins, but the problem is that these are the only things that can appear. Only the reels 2, 3 and 4 can scatter on them. The scatter image shows the chocolate bar and logo.
At this point, 10 free spins can be activated. You can collect Gravy Boats as the reel appears, in exchange, the game converts the candy symbol into additional wildlife, while adding a free spin. With 3 Gravy Boats, you can turn Red Candy into Wild. Seven are collected, orange candy will do the same, and you will trigger 3 extra rotations. Finally, 12 Gravy Boats were collected, turning green candy into wild animals and adding 2 free spins.
