Mole Tank is an ability in Densetsu no Stafy. As it's name implies, it's a tank that looks like a mole. It lets Starfy dig underground. He wears a light helmet when using it. It is taught to him by Mogu. Every time the music loops when riding the Mole Tank not only will the tempo of the music slightly speed up but the Mole Tank will also speed up along with the music making it abit harder to avoid obstacles and enemies.
Only the control pad is used. You can move in all directions as long as there's nothing in the way. Heading straight for an enemy will defeat it if you're in the right direction.
