Tierra is a caring, understanding, very jumpy 5-year-old. Her best friend is Reagan. Her favourite colour is orange, and her favorite food is chicken salad with chives. Like Vitani, she hates being around Opal, her selfish cousin, and shampooing her hair.
Tierra looks almost identical to Vitani except for the fact that her eyes are green while Vitani's are blue. She has light tan skin, deep purple hair done into two low pigtails, and bright neon green eyes. Her full mermaid tail is bright, neon baby blue streaked with thick, wavy orange stripes. She wears an orange starfish bow in her hair.
