Ludo's Army

In season 1, Ludo has an army composed of his loyal monster minions who help him in his quest to get Star Butterfly's wand and take over the universe with it. In "Marco Grows a Beard", Toffee usurps Ludo and takes over as the army's leader. In season 2, Ludo obtains a new army with a giant spider, a bald eagle, rats, and other monsters (which he has enslaved) as his minions. It is unknown what happened to most of Ludo's previous army after the events of "Storm the Castle" (wherein Ludo's castle was destroyed, with most of them seemingly still inside). Some of those shown to have survived, such as Buff Frog and Boo Fly, have pursued other lines of work. In "Starfari", others are shown to have also survived, including Three-eyed Potato Baby and Beard Deer, and relocated to a monster village on the outskirts of Mewni. In "Is Another Mystery", the unnamed two headed monster is also shown to survived when he and the other monsters left Mewni for sanctuary. In "Princess Quasar Caterpillar and the Magic Bell" Ludo is reunited with several monsters of his former army, who rejoin his ranks.
