In episode 68, Mako Tsunami uses this card during his Duel against Joey Wheeler. He Tribute Summons this card by Tributing "Flying Fish". This card then attacks Joey's "Alligator's Sword", but Joey activated "Fairy Box" to place "Alligator's Sword" in a Whack-A-Mole box. Mako then activates "Umi" to force "Alligator's Sword" out of the box since it can't breathe underwater. This card then gained 200 ATK and DEF due to "Umi". The attack continues, but Joey activates "Skull Dice" to roll a die and divide this card's ATK by the result. Joey gets a four, so the ATK of this card is divided by four. "Alligator's Sword" then destroys this card.
The damage calculated between the battle of this card and "Alligator's Sword" was not correct as Mako took 700 damage (which would work only if the ATK of this card was divided by 3.25 which would be impossible as "Skull Dice" divides the ATK of a monster by a whole number that is from 1-6) when he should have taken 850 damage.
