About this creation
The Conga, a submersible contructed by the peaceful Gungans, was used as personal transportation for trips through Naboo's dangerous core. Its propulsion came from two tentacle-like propellers and, in fishy emergencies, a hydrogen rocket. The sub also had the unique ability of transforming into a Kaadu herder of sorts (last few pics).
The sub's intakes fold down to form landing gear.
Kaadu herder form. The propellers fold around and become "Kaadu prods".
The harpoons are there just in case there's a "bigger fish".
