The Toadra

The Toadra is an anomalous secret boss that can be found in some copies of Super Mario 64, spawned by "attacking" a Toad, on any floor of Princess Peach's Castle or area with Toads. The exact "attack" method varies in each report. The Toadra itself is a large mass of Toads with several tentacles, in a similar form of the Smorgs in Paper Mario: The Thousand Year Door.

The Toadra takes up a lot of space, sometimes getting stuck in between walls or being pushed out of bounds. The Toadra itself attacks by smacking the player with it's tentacles, and is damaged by being ground pounded. However, due to it's size, on some occasions it's too big to reach it's top, making it invincible. If it is ground pounded enough, it will break into several Toads that run away.

The reward for defeating the Toadra is the "Mushroom Cap", a special cap that turns the player into a Toad. The exact use for this cap changes in each report, but it is commonly used to get special dialogue with several Toads throughout the game.
