Diss Seal

Diss Seals are genetically modified sea lions that guard the Diss Prison and enjoy attacking penguins on land. They hare black with red spots on their back. Despite their name, they are not seals, and have visible ears and more upright posture. However, unlike most sea lions, males are the same size as females.

Trivia

 * They are a parody of Hellhounds
 * Diss Seals are immune to the Pope's speeches, but are weakened by silver, iron, salt, etc.
 * Cerberus of the Freakishly Big Demonic Monsters of Destruction is a giant Diss Seal who guards the prison more menacingly than the rest.
