Snake (Mother)

The Oh-So-Snake is the boss of Chapter 2 in Mother 3. After Duster, Kumatora, and Wess discover the Hummingbird Egg in Osohe Castle, a trap causes them to fall into the castle moat where the Oh-So-Snake attacks them.

Battle
In the first turn, it is a good idea to use the Smoke Bomb on the Oh-So-Snake to lower the accuracy of its attacks. Try to defend when the snake prepares itself to create a party-damaging wave attack. Have Duster use regular attacks and restore the party's HP and Kumatora's PP. Kumatora should use PK Thunder as often as possible. Bombs also do a lot of damage.
