The Disney G-Force ‘Discover your Secret Inner Guinea Pig’ promotion invites participants to upload their pictures to be turned into one of the main Guinea Pig characters.
Participants will be entered into a draw to win a Wii console as well as the G-Force Wii game.
Rodrigo Cauduro, MD of W3haus UK said: "The project is a great medium for kids to discover the different personalities of each character and become familiar with the G-Force brand in anticipation of the film and game releases."
The website has been created for the build-up to the launch of the animated feature film by Disney, which will happen at the end of the month in cinemas in the UK.
Richard Kinning of Turner Media Innovations commented: "W3haus take the time to ensure they are fully immersed in the concepts behind briefs before they begin to work on them.
“They are willing to take on board suggestions and add their own extra creative twist to them whilst the project is in process.
"This produces work of an excellent standard and we are very happy with the results of this collaboration and will gladly work with them on future projects."
