Goomdiver

Goomdivers are diving-helmet-clad Goombas in Mario & Luigi: Superstar Saga. They appear in underwater locales, such as Oho Ocean. Their names are a combination of "Goomba" and "diver". 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. In the overworld, Goomdivers dive down into view from off-screen in an attempt to land on Mario and Luigi to initiate a battle, though this can be avoided if the player sees a little water sprout on the ground which indicates where they are going to land.

Goomdivers sometimes assist Bloopers in battle. They are also very similar to Aqua Kuribō in Super Mario Land 2: 6 Golden Coins.

Trivia

 * Goomdivers are one of the few enemies to not appear in Minion Quest: The Search for Bowser since they are only able to attack underwater.
