Pigpig the chameleon who lives in Chester Zoo has become a campaign star.
HTC have enlisted the colourful reptile to help launch their latest handset, the Desire 626, and his fee will go towards environmental projects.
Pigpig inspects and uses his camouflaging abilities on the smartphone in the campaign.
Peter Frolund from HTC said: "Chameleons have a unique ability to change their colour to suit their mood, which is something we wanted to reflect in the new phone"
The money paid to Chester Zoo for Pigpig's appearance will go towards projects that help communities across Madagasca to save the biodiverse wildlife within the remaining forests.
