Ragumo

Ragumo are mole enemies that first appear in Super Mario Land 2: 6 Golden Coins. They are likely based off Monty Moles due to their similar appearance and attack pattern and may be related to them, but they are considerably slower.

Super Mario Land 2: Golden Coins
In Super Mario Land 2: 6 Golden Coins, Ragumo appear exclusively in the level Tree Zone Area 1 and can be found in low-lying areas, such as pits or ditches. To attack, the Ragumo will burrow underground and attempt to pop up in Mario's path. However, Mario can swiftly jump before the Ragumo pops up, thus landing a hit on its head. Fireballs can also be effective to defeat it, but only when the Ragumo has surfaced.

Super Mario-kun
Ragumo only appear in two volumes of Super Mario-kun.

A Ragumo appears in the final chapter of volume 6, where when Mario enters Tree Zone, he and his Super Carrot are ambushed by the Ragumo. Mario tries luring the Ragumo with his Super Carrot but the Super Carrot kicks him in the air. Mario then proceeds to attempt throwing fireballs at the Ragumo, but it pops up on the other side. A Bopping Toady helps the Ragumo by pinning Mario down using its tongue. The Super Carrot tries helping Mario but it is quickly destroyed when the Ragumo drills through it. The Ragumo then attempts to drill through Mario, but Mario uses his Bunny Ears to try and stop the Ragumo's drill. As the Ragumo drills, Mario spots a Super Mushroom that he uses to power up his Bunny Ears to break the Ragumo's drill and slap the Bopping Toady. The Ragumo resembles a Monty Mole in this volume.

A Ragumo cameos in volume 10 as one of the enemies Luigi recruits to defeat Wario. The Ragumo's design in this volume looks more faithful to its artwork from Super Mario Land 2.
