Yadokari

Yadokari (ヤドカリ) is a hermit crab-like Mechaniloid that serves as the sub-boss in Tornado Tonion's stage in Mega Man X7. It attacks with homing missiles, fireballs and by launching its claws. When it withdraws into its shell, three large blades appear and rotate around the arena while bobbing up and down. The player will also have to deal with its attacks in the first part leading up to the sub-boss battle, while rescuing several Reploids before they are killed.
