Mammoshka

Mammoshka is a boss in Mario & Luigi: Dream Team. Found near the top of Mount Pajamaja, this mammoth-like creature acts as a guardian for the mountain, and is battled by Mario and Luigi in their journey to the mountain's summit. Its name is a pun on "Mammoth" and "mamushka" (an alternate, erroneous name for Matryoshka dolls), both of which form its basis.

Appearance
Mammoshka appears to be a mammoth-like creature inside an igloo-like armored shell.

History
Mammoshka first appears when Mario, Luigi, Big Massif and Lil' Massif reach a point near the pinnacle of Mount Pajamaja, where it is found sleeping. Big Massif and Lil' Massif both manage to creep around Mammoshka without waking it up, leaving Mario and Luigi to try doing the same. While they tried doing so, Luigi ended up sneezing and woke up Mammoshka, forcing Mario and Luigi to battle it while Big Massif and Lil' Massif fled to the area ahead. A more powerful variant of Mammoshka called Mammoshka X is fought in the Battle Ring.

Battle
In battle, Mammoshka can attack by shoving a giant snowball at either Mario or Luigi, who have to hit it to the other Bro. After each Bro. hit the snowball at least once with the Hammer, the snowball will disappear. If a Bro. gets hit by it however, they'll then be caught on the snowball and sent rolling off-screen inside it, where the player will need to press either or  depending on which Bro. it is with the right timing to jump and break free properly. Taking too long results in Mammoshka ramming the snowball into a nearby pit with the Bro. in it, damaging them. The player can tell who Mammoshka will attack if it hits him or not. If it does, it'll attack Luigi, whereas if it isn't hit, it'll attack Mario.

Mammoshka can also go into the background and ram the cliff-side to summon an enormous rock, which it throws towards Mario and Luigi. The brothers must simultaneously hammer the rock as it falls towards them, knocking it back into the air; after several hits, the rock will fly back at Mammoshka, damaging it. If the Mario Bros. get hit with the rock they will take large damage and may get Dizzy.

Mammoshka can also chase Mario or Luigi off-screen, warping around to appear from the right side in line with the other Bro. If the second Bro. jumps over the Bro. being chased, they'll avoid taking damage; if they fail to dodge their brother, they'll both get trampled by Mammoshka. If the Bro. not being chased jumps right on top of the one being chased, they'll avoid damage and damage Mammoshka in turn.

Another of Mammoshka's attacks is to chase Mario and Luigi down the mountain, trying to suck them into its trunk while gradually moving side-to-side. If Mario and Luigi dodge its attacks, it'll eventually end the chase, but if one brother is sucked in, it'll then be shot out towards the one remaining, who has to then jump over them as they fly down the screen. this attack may cause POW-Down. Then, Mammoshka will try to fake its attacks; the real attack comes when the trapped Bro's head and arms are visible on the end of Mammoshka's trunk.

During the battle, some Block Monolifts may appear to aid Mammoshka. These enemies carry different helmets inside blocks of ice on their heads, and if they're not defeated, they will give Mammoshka a helmet, a spiked helmet, or a pail to protect it from Mario and Luigi's jump based attacks, one of its weaknesses.

When Mammoshka's health is low, its armor will start to crack, revealing a smaller version of itself underneath. Mario and Luigi will then chase the boss as it flees down the mountain, jumping on its head to continue breaking its armor. With proper timing ("A" for Mario, "B" for Luigi), Mammoshka's outer shell will gradually shrink to nothing, revealing the true form of the beast. After one last jump to its head from Mario or Luigi at this point, Mammoshka is defeated.

Trivia

 * If the player fails to jump on Mammoshka during the chase section of the battle twice, it will jump into another outer shell and resume the battle. It will not however restore health after doing this, so one more hit will break its shell again.
