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 "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.

- When asked about the fate of Ludo's monsters at the end of "Storm the Castle", Daron Nefcy stated during a fan meet-and-greet, "I think they might be dead. Maybe not all of them. Some of them probably got out. But I think some of them are dead."
