Penguin Keychain

The Penguin Keychain is a keychain that Minamoto Kou won at The Aquarium, but he gave it to Mitsuba Sousuke afterwards as a gift.

Appearance
The Penguin Keychain seems to have the appearance of a Humboldt Penguin, with a black head and a white border that runs from behind the eye to the joins of the throat. It also has another border that runs from one armpit to the other. It has a white stomach, underarms and top of the feet, but is otherwise a black color. It also has black eyes with a horizontal slit. It's attached to a bead chain from which it's supposed to be attached to keys.
