It's a Knockout, a game show forcing contestants to dress up in oversized costumes, inspired the idea that the characters should "have that element of being completely uniquely, badly designed for the task that we were gonna put them through".[59] The ragdoll physics are deliberate, to avoid "hyper athletic Ninja Warrior characters" and because "falling over is funny".[59] According to Walsh, striking the right balance between funny ragdoll collisions and game performance was critical, because "as soon as you lose the ragdoll-ness of the character, you lose the comedy".[63] The character designs were inspired by the look of vinyl toys.[67]
