The Field Power Bonus rule was also utilized in the first series of the anime. However, it didn't appear to matter what side of the field you were sitting on when playing monsters on certain field squares. The second series anime made reference to monsters with the Field Power Bonus not being affected by attacks that used Magic Cards to power the monster up (such as "Feral Imp" equipped with "Horn of the Unicorn"). While Yugi Muto was explaining the Field Power Bonus, a series of lands appeared on screen, including an unseen "arctic" or snow-laden land.
