Monster High Lagoona Blue Haunt Couture Doll THE RETURN FROM DOWN UNDER Put your fins together for the final doll in the Monster High Haunt Couture Collection – Lagoona Blue! The swim team captain from the Great Scarrier Reef is bringing her laid-back, high-fashion style to the runway. MONSTER SEA. MONSTER SLAY. Lagoona is wearing a layered mermaid-style dress with a ruffled moto jacket. Our designers gave her an aquarium purse with skeleton lionfish swimming inside (don’t worry, alumni … Neptuna is safe at home). LOW TIDE. HIGH FASHION. We made sure the Lagoona Blue Doll had her long hair with blue streaks, and her signature sea-styled seashell earrings complete her look. BEST DRESSED IN ALL SEVEN SEAS Lagoona’s wearing special octopus wedge heels with starfish print socks. This sassy lass with class comes with a doll stand, her Monster High welcome letter, and a screamium diary.
