The Lotus Root is an obstacle that appears in Mother 3.
Its appearance resembles a real-life lotus root, the only difference being its size; the Lotus Roots are bigger than most humans in the game.
They are only seen in the Mole Cricket Hole where they block off several pathways to prevent further progression. After the Mole Cricket is defeated a second time and he befriends Lucas, the cricket will then summon his brothers to eat the Lotus Roots whenever Lucas checks one.
In addition, an unused enemy found in the game's code is named Lotus Root.
