"Brazil, here I come. Thanksss, amigo."
Boa constrictor in Parseltongue[src]

This boa constrictor was a large brown snake that lived at the Zoo. It escaped after the glass on its enclosure vanished.


Most of the boa constrictor's early life is unknown; it was bred in captivity at the zoo, at around 1991 or earlier. It remained inside its tank, waiting to go back to his home in Brazil.

All this changed in June 1991. After Dudley saw the snake and became uninterested, the snake came in contact with Harry Potter, a Parselmouth, who spoke to it. During the course of their conversation, he accidentally vanished the glass in front of its enclosure. The snake slithered free, leading Dudley to think it was after him. The freed boa briefly thanked Harry and told him that it was going to Brazil, the native range of its species. From there, the snake calmly slithered out of the reptile house. It is unknown if it actually made it to Brazil.

Personality and traits

Lonely and bored, the snake found it highly annoying to have zoo visitors tap on the tank's glass front every day. He had also always dreamed of living in Brazil. He also had a rather playful side, as he made a point of snapping at the heels of panicking Muggles as he left his former prison but without intent to hurt them.

Interestingly, the snake seemed to be capable of reading; when Harry asked if it missed its family in Brazil, it pointed to a sign which read RAISED IN CAPTIVITY.

Behind the scenes


Harry Potter talks to the snake

  • In both the book and in the film adaptation of Harry Potter and the Philosopher's Stone, the snake winks at Harry. However, snakes are unable to wink, as they have no eyelids.
  • In the film, the boa constrictor was replaced by a Burmese python.
  • The boa constrictor was rumoured to actually be Nagini; this has since been proven false.
  • The boa constrictor was the only legitimately friendly snake in the franchise, as all the others were villainous in some way.
