Mrs. Wawa is Yaya's mother.
Although she never appeared in the series, her name was first mentioned in Season 1, Episode 5 of the original series when BoBoiBoy Lightning was told by Tok Aba to help him send the cocoa ordered by Mrs. Yah/Wawa, but he mistakenly went to Mr. Mat's house despite carrying map with him. Then, Mrs. Mat helped BoBoiBoy Lightning send her to Mrs. Yah/Wawa's house.
In Season 1, Episode 7, Tok Aba talks with Mrs. Yah/Wawa by phone to allow Yaya to play video games at her home. Tok Aba and Mrs. Yah/Wawa both agree that it is not good to play video games long ago because it can cause the kids not to learn and can spoil the vision. Due to their goal of saving BoBoiBoy and Gopal which included video games, Mrs. Yah/Wawa allowed Yaya to play video games, but only fifteen minutes.
- Both of Mrs. Wawa and Aunty Yang are close friends but very competitive at the same time, just like their daughters.
- Like her daughter, she was also known for making horrible biscuits and gets mad when anyone said her biscuits are horrible.
- Although she was credited as Mrs. Wawa, she had already been addressed as Mrs. Yah by Tok Aba in the original series, implying that her full name is Mrs. Wawa Yah.
