Goomdiver

Goomdivers are diving-helmet-clad Goombas in Mario & Luigi: Superstar Saga. They appear in underwater locales, such as Oho Ocean. They have two different ways of attacking: either they charge directly at either Mario or Luigi, which is countered by jumping, or they swim up and slowly spiral towards Mario or Luigi, which is countered with the hammer. If they swim up, they will continue to be elevated, meaning that only the jump will be able to hit them.

Goomdivers sometimes assist Bloopers in battle.
