just made these animations of the cast of Sonic Superstars to use as emotes on my Sonic the Hedgehog discord server, Let's Talk About Sonic, based on (and edited directly from) a silly dance that the characters of Super Mario Maker 2 do when left idle in that game's World Maker mode
incidentally: Mario, Luigi, and the pair of Toads have very slightly different animations for this in SMM2, which i channeled for these animations. Sonic and Amy mimic Mario's motion, Tails mimics Luigi's, and Knuckles mimics Toad & Toadette's
the inspiration to do this (and to have their frames offset so they make a wave when lined up) came from 1-Up World, a public Super Mario discord server with a lot of good emotes
