I noticed that one of the bobble pods I threw today wound up "wearing" what looked like a black cowboy hat. Are there different variants of bobble pods that can spawn from the thrown item, and are there any differences, if so?

Update: today, one with witch(?) hat spawned (looked like a witch hat with horns). Didn't notice any thing special about what it dropped, but very curious if these have different drop tables or if they're just there for "flavor"
