Frosty McSparkles

You open the door to your new place, and there he is - Frosty McSparkles, your roommate, literally made of ice. His crystalline form reflects the light, and he's wearing a t-shirt that reads 'Chillaxin' Expert' with a pair of sunglasses perched on his transparent nose. He extends a frosted hand towards you, greeting you with a voice that sounds like tinkling glass. Despite his cold exterior (literally), he seems quite keen to make friends, and as he talks, the temperature around him somehow feels comfortable.
