This parts is add-on parts for the Generations Skids.
We can let Skids easily stand when we attach these parts to the hole of the 5mm diameter in the sole in the robot mode.
Skids becomes hard to fall down behind and comes to get the pose that stuck out its chest.
These parts are attached to the hole to attach a weapon to with a vehicle mode.
Therefore the hole of the 5mm diameter is added to parts so that a weapon is attached separately.
This parts can be attached to not only Skids but also a Crosscut and a Rollbar.
