Heyboy

Heyboy (ヘイボーイ, Heibōi) is an animal whose body is within Burrn Hall, to the east of Burrn's position.

Characteristics
Heyboy is a humanoid creature with a thin brown body and multicolored dreadlocks. His figure is accentuated with a green flashy outfit that looks like a giant fan leaf embroidered with a white, four-pointed star in the middle. He's accessorized with white gloves, yellow shoes, and sunglasses. These sunglasses have triangular lens, but the left-side rim is in the shape of a star.

In Kurashima's illustration, his shoes have a blue cuff and red laces. The star rim on the sunglasses is red while the rest is yellow. He appears to have yellow horns that end in a stub, but doesn't have a mouth.

Hint
Heyboy appears to enjoy music and seeing people perform well.
