Inflate-a-Troll was an inflatable model that simulated the appearance of a knocked-out troll, possibly through some Transfigurative process. Draco Malfoy owned one of these in the 1991-1992 school year, and may have been its creator.

Behind the scenes

  • Though not explicitly stated on the card itself, the name "Draco's Trick", along with the card art depicting Draco standing victoriously over the "knocked-out" troll, seems to suggest that Draco used this to try to pretend that he had single-handedly defeated a troll as Harry Potter and Ronald Weasley did that same year.
