Introduction: How to Make a Deadly Cool Torpedo Costume

My teacher gave my grade a project that was made to help us understand the process of design. The scope of the project was to work in a team, create a design, build a prototype and finally make an instuctables on how one could reenact my project. 

Design Brief: I need to build a marine theme Halloween costume that is made of only cardboard through slotted construction and flat pack product design for a middle school aged student.

Specifications:The design for the costume must fit a middle school student. The costume needs to have room for the child to maneuver his or her arms and legs without restriction. The costume must be related to the ocean. The costume must be easy to disassemble, packaged and resembled.

Limitations: The design must be made out of cardboard only, no adhesives at all. The costume cannot be excessive in width, length, height or weight. The Halloween costume has to be marine themed and designed through slotted construction.
