Halloween costumes are expensive, and some of them even cost hundreds of dollars despite just being worn for a one-day spooky event. But Semba and her Chihuaha Mametaro have an arsenal of essentially free costumes made from cardboard boxes. Using creative elbow grease and some leftover cardboard, the dog and human tandem are putting together costumes from Star Wars, One Piece, and even Mad Max.

They both work as a team, and while Semba handles the design, Mametaro poses in whatever costume he's given.
