A miniature Viktor Krum figure was bought by Ron Weasley when souvenir saleswizards appeared next to the campgrounds just before the start of the 1994 Quidditch World Cup final match, which used up all his pocket money (GF7).
Angry at Hermione a few months later, Ron destroyed his figurine of Viktor Krum after the Yule Ball, as Harry finds the detached arm in their dormitory (GF24).
Commentary
Notes
Other Quidditch World Cup souvenirs seemed to lose magical power in the days after the match, so we do not know how long the animated movement of these miniature figures lasts.
