If you were looking for the article about the trenchbilly, then see Betsy.

Betsy[1] "Mama"[2] Krabs[3] is the widow of the deceased Victor Krabs, the mother of Eugene H. Krabs, and the grandmother of Pearl Krabs and has three grandsons (although they have never been seen onscreen with each other). The episodes that feature her have shown her to be very strict and no-nonsense. She is voiced by Paul Tibbitt in her first two appearances and by Sirena Irwin in all her other appearances.


In the same manner, by which all octopodes on the show are modeled after Squidward, Mama Krabs is very similar to her son in terms of appearance. She has wrinkly light red skin, wears a purple dress (she sported a blue one in "Mid-Life Crustacean") and large blue glasses, and has a small patch of fluffy white hair.

In "Sailor Mouth," she has a slightly male voice.

In "Enemy In-Law," Mrs. Krabs is also known not to be greedy, like her son, for when Mr. Krabs greets her, he usually asks her how much money she wants.


Betsy Krabs was born to unknown parents, one of which might have been Mr. Krabs' grandma.

At some point, she married Victor Krabs.

The two had two children, Eugene Harold Krabs, who was born on November 30, 1942, and a daughter born either before or after Eugene's birth.

Victor Krabs either died between 1947 and the events of "Friend or Foe" or Victor divorced Betsy between those dates. If he divorced Betsy and their daughter was not an adult by that point, then he took their daughter with him.

  • In "Stanley S. SquarePants," in a scene, three nephews of Mr. Krabs are shown, who are a parody of Disney's Huey, Dewey, and Louie. This would imply that Betsy Krabs has another son or daughter.
  • In "Enemy In-Law," Plankton falls in love with her due to her grandmotherly appearance.
  • Mama Krabs has a laugh strikingly similar to Popeye the Sailor Man.
  • In the episodes "Sailor Mouth" and "Mid-Life Crustacean" Betsy's voice sounds like an old woman version of Mr. Krabs (while played by Tibbitt), while in the episode "Enemy In-Law," "Spongicus," Friend or Foe," etc. she has a younger Scottish voice (while portrayed by Irwin).
  • It is shown in the episode "Enemy In-Law" she has large muscles after she learns that Plankton tricked her to get the Krabby Patty secret formula.
  • She has a different appearance in the book Mother Knows Best. She wears a pink dress, lipstick, and no glasses, and looks about the same age as her son.
  • She wants to see SpongeBob and Patrick get mauled by the lionfish in "Spongicus." She even states that she "wants to see some body parts!" This shows she likes violence.

  • She has not yet been seen interacting with her granddaughter, Pearl.
    • However, in "Lame and Fortune," they are seen together on-screen but don't interact.
    • Also, she hasn't been seen interacting with her grandsons or her father-in-law, though they were all seen together in "Lame and Fortune" as well but no interaction was made.
  • Unlike her son, granddaughter, and father-in-law, she doesn't seem to have much desire for money, rather innocently asking her son only to be turned down.
