Notes

  • Old Slappy has an increased chance of dropping the legendary Striker shotgun.
  • Like most threshers, Old Slappy takes more damage when its tentacles are destroyed, though they regrow over time. Hammerlock mentions this during the fight.
  • Like Terramorphous the Invincible, Old Slappy has two separate models.
    • When it initially surfaces from the reservoir, Old Slappy will perform a taunt. Being a passive model in this case, Old Slappy does not attack, nor could it be harmed or draw fire from nearby Hyperion units.
    • After the taunt animation has ended, Old Slappy properly reveals itself and can be fought normally.
