In Super Mario Bros. 3, she glows when approached until her kids "explode" away from her, making it harder to swim safely. More kids appear a few seconds later. Just like normal Bloopers, they follow Mario in an attempt to hurt him.

Blooper Nannies reappear in Super Mario Maker, Super Mario Maker for Nintendo 3DS and Super Mario Maker 2. The player can shake or hold a Blooper while editing a level and it will become a Blooper Nanny. It functions identically to a normal Blooper, only with Blooper Babies in tow. Unlike in previous installments, Blooper Nannies do not shoot their babies. Blooper Nannies and their babies can be stomped on if out of water. New sprites for them have been made for Super Mario Bros. and Super Mario World (along with normal Bloopers) styles.
