Bibintiki are five mischievous little monsters with distinct personalities and vibrant appearances.

About the Project
«Bibintiki» is a collection of five vibrant plastic monster toys with unusual features, comical teeth, and multi-colored braces. The toys' special feature is thermo-sensitive bellies that become transparent when the temperature exceeds 36,6 °C, revealing imaginary organs hidden inside. Once cooled, the bellies return to their original color. The project offers an engaging game of unexpected transformations: every Bibintik conceals a unique inner world that can be discovered through heat.


Character Concepts
Thermo-sensitive tummies that turn transparent above 98,1°F, revealing fantastical organs hidden inside. After cooling, the tummies regain their original color.
Each Bibintik conceals a secret that can be unlocked with heat. The main surprise of the collection is a real diamond, planned to be hidden in one of 100,000 pieces, turning it into a unique collector’s find.

Collection Principle
Constant Elements:
• Rounded body shape and proportions • Oversized eyes, playful teeth, and colorful braces • Glossy plastic surface with patches of fur • Thermo-sensitive belly that changes transparency when the temperature exceeds 98,0 °F (36.6 °C)
Variable Elements:
• Color palette and body pattern • Shape of ears, horns, and hairstyle • Facial expression, eye color, and shape • Fantastical internal organs and hidden surprises
Dimensions
Height — 120 mm
Width — 100 mm
Depth — 100 mm
Construction
— Main body: a round, plastic casing featuring a head, limbs, and decorative accents.
— Thermo-sensitive belly: a transparent insert with a thermochromic coating that turns colorless above 36,6 °C.
— Internal organs: voluminous, multi-colored plastic elements secured inside the casing.
— Additional details: eyes, teeth with colored braces, tongue, ears or horns, and decorative fur patches.
— Assembly: individual parts connect and are securely fastened, preventing access to the internal components.
Method of Execution
The project utilizes a thermochromic coating that changes the transparency of the Bibintik’s belly when heated.
1. The toy’s body, the transparent belly insert, and the volumetric, fanciful internal organs are made of plastic.
2. The internal elements are painted, secured within the body, and covered with the transparent plastic insert.
3. A thermochromic coating is applied to the outer surface of the belly; at a temperature below 36,6 °C, it conceals the internal organs, but when heated above this value, it becomes transparent.
4. After cooling, the coating reverts to its original color, once again concealing the contents of the belly.
