For the longest time, she has had a secret softer side: finding comfort in her childhood toy, Señor Squeaky. Although she loved her toy, she feared that if people knew about him, it would make her seem less intimidating.
Lagoona grew up in a remote Castillo with dreams of exploring the world beyond.
Lagoona is a fairly tall, slender, light hot-pink-skinned teenage sea monster with freckles on her face. Her skin sports a cyan gradient on her fin-shaped ears and feet up to her calves.
