The Octopus Uniform is a new uniform that Chiikawa and friends received from Yoroi-San.

The new uniform features a bright red suit resembling an octopus, complemented by a twisted headband. The ears are tucked inside, but surprisingly, it's not too tight and seems quite comfortable.

The palms feature suction cups that can climb walls, but there's no guarantee about getting down. Thanks to Chiikawa and friends walking around in the Octopus Uniform, it seems to have had a good advertising effect for Yoroi-San, who runs a takoyaki shop, and his sales have increased.
