If the point of the tadpole is to make one then switch out chassis we should have some way to store the chassis we arnt using other then leaving them floating around, I propose either a new dock entirely or letting the bare chassis dock at a tadpole dock.

I think a cool concept for this would be a new interior module. Something between a ceiling mounted crane and conveyor belt which can be expanded to hold multiple chassis and can equip the docked tadpole with the chassis you want

Absolutely! I was expecting this!

Another idea along the same lines: have an analogue to the Seatruck Dock from Below Zero–a dock that separates the tadpole from the chassis and makes both accessible from inside the base. Then, if several of those are built side-by-side, the Tadpole could simply “slide” back and forth along the joined docks to deploy with whichever stored chassis the player wishes.
