The smurfmarine is a submarine that was built by Handy Smurf. It was used to dive deep underwater and resembles a large fish. Its appearance so far was on "No Smurf Is An Island," where Handy built one to be able to visit his true love Marina. Later, when Handy and Marina were having a good moment together, a large orange female fish mistook the smurfmarine to be a male of its species, which forced Handy to do a fast back reverse. He bumped it against the cliff and made a big rock fall, sinking the smurfmarine which almost resulted in Handy drowning. Fortunately Hefty used Handy's power drill to get him out before that happened.
