Yeti Cool Brothers

The Yeti Cool Brothers are subordinates of Caesar Clown.

Appearance
From what is seen in their silhouette, they have long legs with fur, have fur on their upper body, wear black shorts and hats.

They are massive in size, as one of their footprints is larger than Brook, who stands at 266cm (8'8½").

Abilities and Powers
They carry one rifle each. Caesar thought it was a bit much to send them to deal with the Straw Hat Pirates, so their strength is presumably quite high.

Punk Hazard Arc
The two Yeti Cool Brothers were summoned by Caesar Clown to deal with the Straw Hat Pirates, and they were first seen outside one of the abandoned labs that the crew was residing in. They appear to have passed by Zoro's group as Zoro, Sanji, and Brook are unconscious around their giant footprints. Whether or not that's due to a confrontation with them is uncertain.
