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 Bloobers, they follow Mario in an attempt to hurt him.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
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.
The Adventures of Super Mario Bros. 3
Nintendo Adventure Book
In the Nintendo Adventure Book Leaping Lizards, two Scattering Bloobers (known here as "Bloober Nannies") compete in the International Mushroom Games as members of a team known as the Sneaks. What events they participate in besides the Beetlebowl, an all-team game, are unspecified.
Super Mario RPG: Legend of the Seven Stars
Only one Scattering Bloober appears in the Sunken Ship during the events of Super Mario RPG: Legend of the Seven Stars; oddly, touching her or any of her babies results in a normal battle with a single Bloober.
