Mrs. Yah is a minor and an unseened character in BoBoiBoy. She is Yaya and ToToiToy's mother. She never had an appearance in the series but her name was already mentioned in Season 1, Episode 5 and Season 1, Episode 7.
- Season 1, Episode 5: BoBoiBoy Lightning was forced to deliver some cocoa but forgot even when he has a map, so he told the Burgerman to deliver it.
- Season 1, Episode 7: Tok Aba was seen talking to her in the phone about Yaya playing video game, because her mom only allows her to play 30 minutes only. Tok Aba and Mrs. Yah mentioned that it's not good to play for a long time because children are not studying and it can damage our eyesight, because the case is to save BoBoiBoy and Gopal inside the game, so she allowed her daughter to play for 15 minutes more.
