Marigomori

Marigomori appeared in 2009 TV series called Samurai Sentai Shinkenger. Marigomori (マリゴモリ): Marigomori is a whiny, introverted Ayakashi with the ability to curl into his snail-like ironclad armor who's bent on making everyone more miserable than he is.

But using a combination of heat and water, the Shinkengers manage to weaken the shell to use the Tora Five Rings Bullet to destroy him. Revived, he is once again weakened by the elemental attacks of Kabuto ShinkenOh and Kajiki ShinkenOh Armament forms, before ShinkenOh becomes Tora ShinkenOh to finish him off. His hard, shell-like armor is the inspiration for the Sazae-oni (栄螺鬼) of Japanese myth.
