A miniature figurine of Viktor Krum, the Bulgarian Seeker, was one of many merchandising products sold at the Quidditch World Cup in 1994. It was animated and could walk. Ron Weasley, a big fan of Viktor, bought one. He soon destroyed it when the real Viktor went to the Yule Ball with Hermione Granger, for whom he was developing intense feelings.
It is unknown if there are figurines of the other national Quidditch players.
