Toadies are Kamek's underlings which have several different classes.
These are red in color and do not appear unless Baby Mario has been in his bubble for too long in the Yoshi's Island games. There is also a pink Toadie that steals Baby Mario when Yoshi is attacked. These ones are like Solo Toadies in that they do not report to Kamek directly.
These are green in color and when they steal Baby Mario do not directly report to Kamek.
Toadies make a small appearence in Yoshi's Story. Whenever the player dies, it takes the Yoshi that was hurt to Bowser's Castle.
