Product Idea

Small Cargo Submarine

It is a small cargo submarine with a crew of two. It can carry cargo and has two containers with the build. It has fold out wings to go underwater, two beds and a table with a hotdog and a slice of pizza. 
I built it because I saw one of the new Lego sets for 2020, and saw the two hulls. This inspired me to make my own version, but with a twist of it becoming a   submarine. 
I think it would make a good Lego set as it is a simple build, with lots of functions and a nice look.
