The item in Brother Octopus's hand was the special, one-of-a-kind item: Red Heart A. Its function was to allow its wielder to teleport anywhere they wished. For example, Brother Octopus's initial goal was to obtain more Ninth World link nodes, so Red Heart A brought him to the island. It even followed him directly after Shen Fei entered the city.
Brother Octopus's second thought was to chase Shen Fei. After Shen Fei teleported away, he simply appeared out of thin air in pursuit. His final thought, when faced with Shen Fei's Invincible attack, was to flee for his life immediately. And so, Red Heart A instantly whisked him away, allowing him to escape the range of the Defense Tower's Cluster Attack—an attack that had never been evaded before.
