Ragumo

Ragumo are mole enemies that appear in Super Mario Land 2: 6 Golden Coins and various Mario Manga related to said game. 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
Ragumos 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
Ragumos only appeared in two volumes of Super Mario-kun

A Ragumo appears in the final chapter of volume 6, 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 it’s tongue. The Super Carrot tries helping Mario but it’s quickly destroyed when the Ragumo drills through it. The Ragumo the 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. Ragumo resembles a Monty Mole in this volume.

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