Marsupial robotics is a field which requires a high initial investment prior to experiments. We present a new simulation tool used for marsupial actions, enabling research in the area of marsupial robotics. A flexible abstraction for a marsupial system is presented which allows for the modeling of many differing marsupial models. The interface and simulation model are covered in detail. Two experiments are presented which use the model to demonstrate the flexibility and range of the abstraction and simulation.
