In episode 139, Jim Crocodile Cook uses this card during his duel against the Supreme King. He Normal Summons this card on the first turn of the Duel. This card's effect then activates, inflicting 500 damage to the Supreme King. Later "Evil HERO Inferno Wing" attacks this card, but Jim activates "Sakuretsu Armor" in an attempt to destroy "Inferno Wing", but the Supreme King states that since "Inferno Wing" was summoned via "Dark Fusion", it can't be destroyed by Spell or Trap Cards this turn, so "Sakuretsu Armor" is destroyed. "Inferno Wing" then destroys this card. "Inferno Wing" then inflicts piercing damage to Jim. The second effect of "Inferno Wing" then activates, inflicting damage to Jim equal to "Shell Knight's" DEF (as this card's DEF was higher than its ATK). Later Jim activates "Fossil Fusion" to banish this card and "Elemental HERO Burstinatrix" from both players' Graveyards in order to Fusion Summon "Cenozoic Fossil Knight - Skullger".
Its effect is called Shell Burst in the original and Shell Burst Barrage in the dub.
