The new yellow submarine

So this submarine was originally made of a much smaller submarine, but i added on to make it twice as big.

above is the whole submarine which is about two feet long

above is one of the six engines and an oxygen tank with a turret-mounted spear gun in front of it.

this is the standard 30 mm machine gun

inside is the seats, a scuba tank, several guns for protection, and tools to fix the rudder..

this is the front with four more spears, an opening hood, and a hidden torpedo under the hood
