Here is what the packaging would have looked like for the twirling TV above. It's the green bag (labeled "Sonic" but harder to see)

There were several different Happy Meal boxes printed for the promo. Each box had a different theme on each side to promote 1 of the toys from the line. This is Sonic's side. Each had a little game/puzzle/riddle thing to do. Sonic's is a "Connect the Dots" It says "It's a surprise party, connect the dots to see who's coming!" (well clearly Sonic) The joke at the top says "What do you get when you combine ice-cream & a balloon? A real cool float."

What's going on with that terrible Robotnick art there at the bottom? He's almost abstract in his terribleness. 2 really huge beaver-like teeth, the mustache has gone wild, his fists are like boxing gloves and the eyes are just...not on model to really anything. Do you want to see a documentary / expanation of this promotion? Lucky Penny Shop has Happy Meal Documentary that you can watch.
