Mogura Mario

Mogura Mario is a transformation that Mario comes across in Super Mario-kun volume 1.

Upon reaching a wall that blocks Mario from proceeding in the level on ground and in the air, Isshī gives him another of the hypothetical Super Mario Bros. 5's power-ups, which transforms him into Mogura Mario to let him proceed underground (due to the absence of Warp Pipes). In this form, Mario wears a Monty Mole costume and can dig through the ground.
