Twinmold

is the MM3D: of MM3D: in. The colossal monster is responsible for all of the curses placed on MM3D:, and is keeping the last of the MM3D: captive. MM3D:'s body is protected by an exoskeleton that leaves only its head and tail exposed.

Characteristics
MM3D:'s MM3D: room is located above the room where the MM3D: is fought. To defeat MM3D:, MM3D: must attack its vulnerable heads and tails. The most effective method for defeating MM3D: is to use the MM3D: while wearing the MM3D:, which allows MM3D: to grow to the size of MM3D:. However, MM3D: will not be able to use MM3D: while using the MM3D:. As the MM3D: drains MM3D:'s MM3D:, MM3D: can replenish it by destroying the pillars found throughout the area, which contain NaN Magic Jars. It is possible to defeat MM3D: without the MM3D: by shooting NaN Arrows at MM3D:'s weak points. NaN Ice Arrows are effective against MM3D:'s red tail, as are NaN Fire Arrows against its blue tail.

If MM3D: strays too far from the initial platform during the battle, even if he is wearing the MM3D:, he will sink into the MM3D:. This causes him to be returned to the MM3D:'s entrance. MM3D: may fly past this boundary in an effort to lure MM3D: into the trap.

Once MM3D: has dealt sufficient damage to one half of MM3D:, its body will explode, with its head crashing into the MM3D:. Once both parts of MM3D: are defeated, MM3D: will receive a MM3D: and MM3D:, freeing the final MM3D: who was trapped in MM3D:'s body. MM3D:'s defeat lifts the curse on MM3D:, causing the undead monsters brought to life by the curse to disappear.

In, MM3D:'s spikes are colored blue and red. The blue MM3D: must be defeated by shooting NaN Arrows at the eyes beneath it. This will make it fall to the ground and reveal its main eye. Once defeated, a MM3D: containing the MM3D: appears in the center of the arena. The red MM3D: can shoot fireballs and summon NaN Moldbabies, which leave NaN Hearts and NaN Magic Jars when defeated. NaN Moldbabies can be defeated easily by bashing the ground by holding the B Button as a giant.

While in giant form, MM3D: can throw punches and roll in order to hit and stun MM3D:. In order to stun MM3D:, it has to be hit ten times or hit with three combos to knock him down while he is flying. If MM3D: burrows while flying, the stun counter will reset. Alternatively, MM3D: can throw one of the two giant NaN Boulders at MM3D: to stun it immediately. When stunned, MM3D: can grab its tail and spin it around, leading to a whip onto the ground, or choke it by grabbing its head. When spinning or choking MM3D:, more damage is dealt when spinning the Circle Pad around.

Nomenclature
MM3D:'s name may be a reference to NaN Moldorms, with "Twin" referring to the fact that there are two of them.
