Creature from the Black Lagoon: One of my brother's friends dressed up like this last year - he looked great!!! Get some old green or black sweats. Hot glue leaves or material in leaf patterns all over. Make a tail with a piece of wire covered with leaves. Paint face green, and mess up hair or get a mask! Good Luck! Thanks to gymnast of the MGFC for this creepy idea! Deep Sea Creature Mask Includes one mask.
