Example Contestants

Example contestants are Yellow Faces (previously armless silhouettes that resemble Golf Ball) that show off how challenges are supposed to be played out, and sometimes used to show some other mon-challenge related things.

Appearance
In BFDI, they were green armless balls with no features that had a strong resemblance to Golf Ball. They were first seen in Cycle of Life to show off the challenge]].

In BFB, instead of being objects, are Yellow Faces, but are noticably more expressive and have more movements. They are typically yellow, but as seen in What Do You Think of Roleplay?, they can be chartreuse or cyan.

Coverage
They made their debut appearance in Cycle of Life.

They were seen again in Rescission to show off how Immunity works.

They made their return as Yellow Faces starting in Four Goes Too Far.

They made their first (and only) non-contest usage in The Liar Ball You Don't Want to show that sound can't come out of a Jawbreaker.

They were seen again in What Do You Think of Roleplay?, with different colored variants.
