April's mom

Buried Secrets: After realizing that there was a trapdoor (which she originally didn't know about), April & Casey and the Turtles investigate this basement. They make a shocking discovery: a Kraang Stealth Ship! Upon further inspection, they find a stasis chamber containing the figure of a woman. After accidentally pressing a button, Mikey releases this woman. It was undoubtedly April's mother. However, Mikey is suspicious and decides to take a closer look. He realizes that it actually isn't Mrs. O'Neil, but a Kraang clone of her. Eventually, the others find out and Raph names it "Mom-Thing". Sadly, they all get eaten by it and become Mom-Mikey-Donnie-Leo-Raph-Casey-Thing. However, just as April is about to be added to the mixture, she releases her psychic wave. Mom-Thing is last seen exploding into green goo because of this. While the real Mrs. O'Neil does not appear, we still learn much about her in this episode, such as what she looks like.

Appearance: As seen in Buried Secrets, Mrs. O'Neil has short blonde locks with dark green eyes. She wears a little blue and pink necklace around her neck and a hanging locket also. She is featured with a purple vest and a black shirt. To top her feet, she wears gold and bronze heels. In disguise, Mom-Thing is an exact replica of her.
