Not really an electronic item, nor is it an ad, a cameo or a retail display...this is a start-up screen. If you use Netflix service for your PC, smart TV or (in this case) WiiU, and select the "Netflix Just for Kids" area, various (in their opinion) Kids Characters show up...and, well here's Sonic! But notice! They took that mysteriously re-occurring "Blue Arms Mistake Sonic" who frequented Australia & also for some reason the Sonic Underground box art.
Ironically perhaps, Sonic is the most innocent one there, as Rocko's Modern Life was frequently fairly raunchy & Ren Stimpy were frequently quite awful.
