Roblox Face Default. For faces that are in the catalog, but weren't released for the public, see unreleased faces. Nope, only the default face sadly, only way would be like an.exploit (not sure), but yeah, not possible.
Make sure the background is transparent! The free smile you can get off of the catalog was one of many faces that were made to update many old, classic roblox faces. The default face is one of the most recognizable things on roblox, so if they permanently replaced it with the revamp, a lot of players would've been quite upset.
