The debut video game for the Moshi Monsters brand has enjoyed strong first weekend sales, topping the Nintendo DS handheld chart.
Moshling Zoo fought off competition from titles including Call of Duty: Modern Warfare 3, Cars 2 and Super Mario Bros to take the number one position in the Nintendo DS top 40 (full price) listing.
The game also made number seven in the top 40 all formats chart (week ending November 12th), outselling titles including Batman Arkham City, Forza 4, Pro Evolution Soccer 2012 and Lego: Pirates of the Caribbean.
"We're thrilled to have become the best selling DS title in the UK," said senior brand marketing manager, Andrew Matjaszek. "To outsell triple-A titles is amazing. We're so pleased our fans have responded so well and look forward to seeing how things go in the lead up to Christmas."
A limited edition of Moshi Monsters: Moshling Zoo is currently available from GAME, while stocks last.
