Squirt is a purebred Chihuahua with a small frame, large bat-like ears, tiny legs, and a skinny tail. His light tan fur contrasts with his spiky black collar adorned with a silver bone tag. Despite his size, he's street-smart, tough, and a savvy negotiator, often muttering "Ah, Sheez" when frustrated. Squirt has a penchant for snarky, sarcastic remarks, particularly towards his teammate Strudel, and can be quite stubborn with his prejudices. Nonetheless, he cares for his teammates.
