Winning Moves has teamed up with Mind Candy's online world, Moshi Monsters, to create a special Top Trumps edition.
The new £3.99 pack includes 30 Moshlings, monster pets and rates them according to their rarity, cuteness and brains.
"To be one of the first licensees to market with Moshi Monsters Top Trumps is extremely exciting," said Fiona Hortopp, marketing manager for Top Trumps. "This is a great brand to add to our long list of top licences and with such a huge existing global audience, we expect Moshi Monsters Top Trumps to become one of this year's must-have children's gifts."
Michael Acton Smith, CEO at Mind Candy, added: "We are thrilled to team up with such a popular brand as Top Trumps to bring the virtual world of Moshi Monsters to life in a new and fun way."
