A portion of a WiiFolder interview with Ubisoft…
WF: Could you explain what ‘Stickers’ do in the Customization? It seems the Rabbids Channel features a section for them, but nothing appears. Do players win these in contests?
Ubi: The Rabbids Channel’s section for stickers is made to give to players some free downloadable content to help them to customize their figurine for specific contests. For example, for the Rabbids Zoo contest we will provide some “fur” stickers, the cougar and the zebra. After getting them, you’ll find them in the Wii remote feature using your normal stickers (page 0).
Be sure to check this section before each contest
