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 brown hair (that has multiple pink curlers in it), glasses, a big yellow shirt with orange frills and polka dots, light green fins, and a rod on her head with a lure at the end (which resembles a light bulb).
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 attempted to marry Mr. Krabs against his will. It is unknown if they are actually married.
In the end of the episode, she became nicer after going to the Krusty Krab.
