Ma Angler (or simply "Ma") is a fat trenchbilly fish. She only appears in the episode "Trenchbillies."
She is a fat dark teal trenchbilly fish with untidy hair, creepy yellow eyes, a big shirt, regular fish tail without feet, and an angler fish antenna.
Ma Angler appears as the main antagonist of the episode Trenchbillies. She is lazy and therefore is pushed around on her couch by somebody else. She says the gang will kill SpongeBob and Patrick if they don't pass the gang initiation ("To deem them worthy....of livin'!") She then appeared at the end of the episode at the Krusty Krab, having somebody shovel Krabby Patties into her mouth while Mr. Krabs watched. The trenchbillies thought he wanted to marry her so the last scene is her and Krabs' "marriage."
Ma Angler is an anglerfish, fish which usually reside in ocean trenches or generally deep areas in the ocean. Anglerfish have appendages on their heads which have a light at the end for attracting prey.
Despite being an anglerfish, she is often lazy and lies on the couch at all times.
She does not have legs at all.
She attempted to marry Mr. Krabs against his will. It is unknown if they are actually married.
In the end, she became nicer after going to the Krusty Krab.
