Bake the cake mix in a 9x13-inch pan according to the box. Cool completely.
Crumble the cake into fine crumbs in a large bowl. Mix in the frosting until the mixture holds together like dough.
Roll into 1 1/2-inch balls. Chill 1 hour.
Melt the candy melts. Dip the tip of a lollipop stick in the coating, insert into a ball, and chill 15 minutes to set.
Dip each pop fully in the white coating, letting the excess drip off. Press a candy eyeball onto each pop before the coating sets.
Stand upright in a foam block until firm.
