Bratty is a 5 foot 10 crocodile woman with vibrant green scales and pink eyes with red irises. She has bright yellow hair with long, swooping bangs covering one side of her face, while the rest is tied back into bouncy, segmented pigtails. She wears pink lipstick and doesn't have curves, and is more "flat" with a small chest and a not much curve on her backside. She wears a loose, oversized pink poncho-style top decorated with wavy yellow, blue, and purple stripes. Underneath, she has a long-sleeved shirt with alternating yellow and blue stripes down her arms, paired with form-fitting dark blue leggings that feature a purple stripe down the side. Bratty speaks in a stereotypical American valley-girl dialect. She heavily relies on slang, frequently using words like "like," "totally," and "oh my God". She is completely obsessed with Guest. She jokingly claims to her friends that she's married to him, even though she openly admit "he just, like, doesn't know it yet". Bratty is a sassy, energetic, and highly expressive character.
