Get away from us, you — you — you WEIRDO!!!

Cindy Sneedly is Gaylord's wife and Melvin's mother. She is the matriarch of the Sneedly Family and like her husband, she is a skilled scientist and inventor.


As mentioned before, she is a scientist who spends most of her time conducting experiments. She is very dedicated to her work. Due to her being fixated on her work, she pays barely any attention to her son, as shown when she paid no mind to his promise of revenge on George and Harold.

Despite that, she truly loves her son, as she was happy to see he was alright after he was chased by the bionic robot boogers and was brainwashed with the Forgetchamacallit.


Captain Underpants and the Big Bad Battle of the Bionic Booger Boy - Part 1: The Night of the Nasty Nostril Nuggets[]

When Melvin turns into The Bionic Booger Boy, he gets defeated by Sulu the Bionic Hamster. Mr. Sneedly takes George's advice by switching the batteries in the Combine-O-Tron 2000 so that Melvin can return to normal. It takes 2 blasts from the Combine-O-Tron 2000 to separate things. Also, before Melvin transforms himself with Combine-O-Trom 2000, it shows her and her husband doing a secret experiment for the government, which apparently included Pop Rocks.

Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy - Part 2: The Revenge of the Ridiculous Robo-Boogers[]

Everyone prepares to go home, it becomes obvious that there was a mistake with the Combine-o-Tron 2000, and now Melvin and Mr. Krupp have switched bodies. Several jokes are made with this outline, including "Kruppy the Kid" (Mr. Krupp in Melvin's body) roars and Ms. Anthrope to give him coffee or he would fire her. Seeing only a fourth grader, Ms. Anthrope gives him a wedgie. As for "Mr. Melvin" (Melvin in Mr. Krupp's body), he is also the basis of some abuse as he runs to hug his mother, who only sees a guy in his underwear coming to give her a hug, and promptly and ruthlessly assaults him with her purse  George and Harold go back in time two days and retrieve the Combine-o-Tron after it gets Melvin and Mr. Krupp back to normal, but before it is smashed (they replace it with a look-alike).

The Epic Tales of Captain Underpants[]

In "The Troublesome Treachery of the Thieving Toot Fairy," she sees Smartsy Fartsy and the boys, then invites them for dinner. During dinner, she can be seen flirting with Smartsy Fartsy.

In "The Bizarre Blitzkrieg of the Bothersome Butt-erflies", when Melvin prepares to create a group of Crocobats, she asks him if he wants meatloaf. Later, when George, Harold, and Captain Underpants use the Time Toad to send the Butt-erflies to the future, she says they're really putting away some "walloaf."

The Heartbreaking Havoc of the Haunting Hack-A-Ween[]

In a flashback, Gaylord and Cindy send Gooch to Melvin's house for a playdate. Melvin, uninterested, steals the five dollar bill Gooch was holding and leaves.

The Xtreme Xploits of the Xplosive Xmas[]

In a flashback, she asks a young Melvin if he wants to share his hamnog, which he refuses to do so.


  • In the books, she doesn't look anything like her son and husband, however in the TV series she appears similar to them.
  • She is shown to be ridiculous as in the books she smacks Melvin when he swapped bodies with Mr. Krupp instead of fleeing. However in the TV series she is much more sensible and nicer.
