The Iwamodoki[1][note 1] is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, hermit crab-based Badnik model created by Dr. Eggman, and the counterpart of the Iwamodoki from an alternate dimension set in the recent past.


Based on hermit crabs, Iwamodokis have a pink and silver body with two cartoonish eyes. Their "shells" are also disguised as a rock, the color of which matches the scenery of Lava Reef Zone.


An Iwamodoki in Lava Reef Zone Act 1, from Sonic Mania.

In Sonic Mania, and its expansion Sonic Mania Plus, Iwamodokis are enemies found in both Acts of Lava Reef Zone. In gameplay, they mostly remain stationary under rocks. When the player gets close enough though, the Iwamodokis will open their eyes and prepare to self-destruct, flashing briefly in the process. Eventually, the Iwamodoki will explode into a rocky shower that can damage the player upon contact. However, these rocks can be deflected by wielding Shield-derived power-ups or through Mighty's Spin Attack. Also, in Lava Reef Zone Act 2, there are machines that produce Iwamodokis and deposit them on Conveyor Belts, making them harder to dodge when they detonate.

Iwamodokis cannot be destroyed by any means, and do not release an Animal or grant the player points upon their destruction.

Powers and abilities

Iwamodokis can self-detonate themselves as their method of attack, though at the cost of themselves.
