Collectible Quidditch Player Figures are lifelike miniature figurines that are able to move around and act like the original person on which they are based. The Quidditch versions are sold as souvenirs during important matches.
Many of the Quidditch World Cup souvenirs seemed to lose their potency after the match - such as the squealing rosettes luckily losing their voices - so it is not known how long the miniature figures would last. Ron destroyed his figurine of Viktor Krum after the Yule Ball, so we don't know whether it still had any movement left by that time (GF24).
