Star vs. the Forces of Evil Wiki

Buff Frog, real name Yvgeny Bulgolyubov,[1][6] is a former member of Ludo's army who spied on Star Butterfly in addition to taking part in the battles against her and Marco to steal the wand. As of season 2, he raises a family of twelve adopted tadpoles and works with Boo Fly.


Buff Frog is a large pale green humanoid frog with yellow eyes, dark green lips, and webbed wings on each side of his head. He has a bulky upper body, but disproportionately short legs. As of season 2, he appears to have gained weight.

In season 1, Buff Frog wears spiked circular shoulder pads, a dark green tunic with a winged eyeball (Ludo's family crest) on it, and a black belt. From season 2 onward, Buff Frog wears a new tunic, which is a lighter green than his previous one and has no shoulder pads, and a gray belt with a skull buckle.


During his service to Ludo, Buff Frog is extremely loyal to him, often fighting for and defending him, but also slow-witted at times. In "Star Comes to Earth", he mistakenly believes Star to be defenseless on Earth and disregards Marco as a credible threat, and in "Match Maker", he believes Star to be "distracted".

Despite this, he is also among the more intelligent members of Ludo's army, being the only one to realize that Toffee has ulterior motives. He also helps Star get into Ludo's Castle in "Storm the Castle", treating her like an equal, fighting alongside her, and even sabotaging Ludo's attempts to get the wand from her, acknowledging that stopping Toffee is more important.

After becoming a parent, Buff Frog shows great love and care to his adoptive children, wanting only the best for them. He demonstrates more compassion than before, as he is unwilling to torture others for information. He has also discarded all loyalty towards Ludo; when Ludo attempted to recruit him again, Buff Frog punched him in the face, believing Ludo had lost his mind. This is further shown when he sends letters to Star to warn her about Ludo and gives her a map on Ludo's old hideout.

By "Puddle Defender", Buff Frog is very good friends with Star, offering her and her mother a place to stay while they are on the run from Toffee. In an effort to prove to Queen Moon that not all monsters are bloodthirsty and vicious, he sides against Star and keeps her locked inside his house.

In seasons 3 and 4, Buff Frog supports Star's efforts to bring Mewmans and monsters together, but believes it is all but impossible, leaving Mewni with many other monsters to avoid persecution in "Is Another Mystery", and showing much cynicism when Star attempts to foster good will between Mewmans and monsters in "Cornball!". Only when he sees monster and Mewman children (including his own tadpoles) playing together does Buff Frog start to believe there is hope (for the next generation, at least).

  • Buff Frog speaks in a thick Russian accent, fitting his real name, which is Russian.
  • His name and species is derived from the bullfrog, a type of frog known for its aggression, gluttony and large size.
  • He is the first of Ludo's minions to appear in an episode that Ludo himself didn't appear in.
  • In "Mewnipendance Day", it is revealed that he was taken in from the swamp after being rescued by Ludo.
  • He was the only one of Ludo's minions who did not trust Toffee (which drove Toffee to engineer his banishment).
  • In "Storm the Castle", he becomes the adoptive father of a group of tadpoles.
  • As of season 2, Buff Frog is acting on his own accord.
  • Both "Is Mystery" and "Raid the Cave" show that Buff Frog has terrible penmanship, to the point where Star and Marco thought the letters he sent Star warning her about Ludo had been fan art written by his tadpoles. In "Is Another Mystery", Star acknowledged that the farewell letter she found couldn't have been written by him, because it was far too legible.
  • In "Puddle Defender", Buff Frog reveals he has a tattoo of Ludo above the word "FOREVER" under his left breast.
