So I'm flying through course "City Escape" and when I get to the stairs of where you would find a chao key container in the original game, I notice something
There is a missing poster at the bottom of the stairs
Upon closer inspection. What I can make out is 2 pictures of people from the sonic Universe:
Classic Super Sonic
And
Mighty the Armadillo
My eyes may be tricking me but take a look for yourselves!
Is this a little easter egg put there by Sonic Team?
