Squidward's brother is a squid(technically octopus) that possibly lived in or near Bikini Bottom. He is the brother of one of the main characters : Squidward Tentacles. He never appeared so far on the show.
Almost nothing is known about Squidward's brother before or as the outbreak began except that he owned a clam-shop and fifteen boats.
It is unknown what Squidward's brother did to survive when the dead began to rise IF he even survived at all. It is possible that he could be a walker and Squidward doesn't know about it.
Squidward mentioned his brother to Spongebob and the group in Season 4 when they were desperate for sanctuary. Squidward said his brother owned a clam shop on the coast and he also stationed fifteen boats on the water and Squidward hoped it would be a good shot for sanctuary. However, later on, they only found five of the boats, the other ten must've been stolen by people in the early days of the outbreak in a mass panic.
This list shows the victims Squidward's Brother has killed:
- Possibly a few zombies.
