The Tattletale Strangler is a large, buff green fish with a unibrow and serial killer and lives in Bikini Bottom. He is notable for strangling his victims after they rat him out, hence the name. He pretended to be SpongeBob's bodyguard and tried to strangle SpongeBob many times after SpongeBob told on him for littering. His first appearance was in "SpongeBob Meets the Strangler." Note some strange similarities with Dennis.
"What are you going to do, call the police?"
"Can we just go to your house?!"
"Open the door so I can strangle you! Uh, uh I mean protect you."
"Forget the key! Let's climb through this window... I can't reach it. Do you think you can hop on my shoulders kid?"
"Cleats? *SpongeBob falls on his eyes* AHHHHHHHHHHHHHHHHHHHHHHHHH! GET YOUR FEET OUT OF MY EYE SOCKETS!"
"Close the door!"
He's not the strangler! *rips off the fake moustache* I AM!"
"Oh, it's a fake, you idiot!"
"Look kid! I'm not your bodyguard! *cries* I'm the strangler!!" *cries* See?!"
