Toad Guards are minor characters in the SMG4 series.
They usually stand in front of the Princess Peach's Castle to protect the Princess Peach, and keep Mario out whenever he is ordered not to come in the castle. These characters are similar to the guards which protect an official residence of a high-ranking official like a king or president.
Their main and debut appearance in SMG4's bloopers is in the episode "Super Mario 64 Bloopers: Master of Fail Disguises", where after Mario destroys the castle, Peach puts out two Toad Guards to stop Mario from coming to her birthday party, so Mario tries to sneak in with some disguises, however ultimately fails. One appeared again in the video "Birthday Freakout" to keep Mario from coming into Roprinplup14's birthday. Later some appeared in the blooper "Super Mario 64 Bloopers: A Fungus Among Us", but this time they had glasses and a black and red afro.
- In the real Mario video games, the Toads protect the Princess by keeping Bowser out of the Castle, and not Mario.
