Aside from its color, the wobblebobble is identical to its counterparts. The box has a slightly darker shade of yellow, with the wobblebobble's decal on the front and back.
The wobblebobble is based on a Roblox hat called "Bighead".
The wobblebobble has a strange property, where it stays upright in an intended position. It can also be hitched onto vehicles and will bobble around the attachment node when the vehicles are in motion.
A popular rumor states that it helps balance vehicles and prevent them from flipping, however, this is untrue. Because of it being a loose item, it can freely be used as decoration or for showcasing purposes.
