From the Super Mario Wiki
Solo Toadies are Toadies that travel singularly in the game Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. Unlike Kamek's red-cloaked Toadies, Solo Toadies are green or dark pink, and their feet are always visible, unlike the red Toady sprites. The green Toadies can be found floating around in a select few levels, and when encountered by a Yoshi, they will try to snatch away Baby Mario. The dark pink Solo Toadies are even more rare, and only appear after Baby Mario has been knocked off Yoshi, at which point the Solo Toady appears and attempts to hold the baby out of reach of the Yoshi. Neither type of Solo Toady will fully kidnap Baby Mario, but they will try to separate him from Yoshi long enough for Kamek's group of Toadies to take him away.
Solo Toadies reappear in Yoshi Touch & Go. Here, instead of trying to snatch Baby Mario, they will try to defeat Yoshi. These Solo Toadies appear only in green coloration.
