He first appeared inside the Cold Storage with his two henchmen. His plan was to befriend all of the Vanillite residing in the Unova region with frozen food. He later appeared when Linda was investigating the Cold Storage and took her hostage. In an attempt to run away from the gang, he took on the alter-ego Cryogonal Man (Japanese: フリージ男Freege Man) with a Cryogonal mask on his face.
Despite all of that, he did not succeed in his plan and ended up being arrested for his criminal deeds.
Despite wearing a Cryogonal mask, Dr. Ferrara's only Pokémon was a Vanillish (which he admitted was due to his inability to catch a Cryogonal), which appeared at the climax of the episode. It battled Charles's Accelgor, but was knocked out by Accelgor's Swift.
