Squilliam is a guest character and a survivor of the outbreak in TNT's The Spongebob Dead.
Almost nothing is known about Squilliam's life before or as the outbreak began EXCEPT that he was an entrepreneur of many fancy jobs and was a trillonaire. How he got an unbelievable amount of money is unknown but he possibly worked hard for it. He was also the arch-rival of Squidward.
This list shows the victims Squilliam has killed:
- Pearl Krabs (indirectly caused)
- Possibly numerous counts of zombies.
- This character was the first character killed by Old Man Jenkins despite it being a mercy kill.
- Squilliam has the same voice actor as Bubble Bass. They are both voiced by Dee Bradley Baker.
