Dream Tender (ユメナマコ) is the captain of Zone Nu from G-Darius. It's shaped after a Swimming Sea Cucumber (Enypiastes).
This captain's main form of attack is to shoot a pair of wave shots which move forward in a waving motion, crisscrossing each other. Its secondary attack is to shoot floating mines which detonate in a large explosion. When captured the floating mine attack is executed by inputting a "Dragon Punch" backwards motion (←↓↙) the pressing/holding the shot button.
