Do you guys even notice a little reference in these three pictures here?
See any similarities between this and the other three?
See another noticeable reference circled in red?
Look closely at the image with the red border around it. Does it seem suspiciously familiar?
Another shot of the ring-a-bell image.
What's even more strange is that in the beginning of The Amazing World of Gumball short, "Gumball's Wonderful Day", Darwin, Nicole, and Richard don't even bother noticing it (or maybe they have, but ignored it).
Hidden Emblem[]
See what emblem is it on the car right there?
The hidden logo circled in red (see it in full-screen mode and hint: that hidden logo is from a real car company).
