For this easter egg, you must unlock Sonic (Complete the Subspace Emmisary or play 300 ys. mode characters), which will unlock the Green Hill Zone.
While fighting in the GHZ, look at the loop in the background. At some point, you will see Kunkles, Tails, and Silver in the background (Tails will be the most noticeable).
Even the official website of SSBB mentions it!
Just look in the background in the video.
