Two characters. 鸡 (chicken) has the party guy here dancing the funky chicken. You can see because the right part looks a bit like an S.蛋 (egg) is a bit abstract but bear with me.We've got the air chamber at the top, the yoke at the bottom and then there's the eggwhite sort of swimming around that and it's attached to the shell at the top. The yoke is trying to break out of the shell because I guess this egg was fertilized and that yoke is now a chick.
