Snail Blaster (スネイル・ブラスター Suneiru.burasutā?), renamed Den-Den (デンデン Denden?) in Japan, is a snail-type badnik (hence its name) created by Doctor Robotnik. Snail Blasters have made first appearance in Sonic the Hedgehog 3. These badniks have grey head and green and red colored shell which includes two laser blasters inside of it.
Sonic the Hedgehog 3
In Sonic the Hedgehog 3, Snail Blaster will stick to the walls in Launch Base Zone. When the player approaches, it will open its shell and fire energy balls out of two hidden cannons - at 45 degrees above and below horizontal. After this it will close its shell again. It can only be destroyed with Spin Jump while the shell is open, and is otherwise invulnerable.
Sonic Lost World
Snail Blasters appear in Sonic Lost World, where these badniks are featured at Windy Hill. While these badniks are not seen moving on walls, they are moving slowly to the lateral direction on the ground and on the certain point, it stops and shoots two energy projectiles towards. The player is able to destroy them easily by performing an unnamed kick attack. In 2.5D format acts, Snail Blasters aren't seen usually moving on walls, but instead they are able to roll towards the player, when Sonic is close enough to them.
During the game, it turns out that badniks, Snail Blasters included, got hijacked by the Deadly Six. Snail Blasters and Buzz Bombers are seen to be first badniks to do so at Desert Ruins, who turns against the Doctor and gets commanded to fire by Deadly Six. Few of them gets destroyed by Sonic, but the predominance of badniks and Deadly Six forces Sonic, Tails, Eggman, Orbot and Cubot to retrieve.
Sonic the Hedgehog: The Movie
Snail Blasters also appear in Sonic the Hedgehog: The Movie, where these badniks ambushed Sonic, Tails, and Knuckles while they were hurrying to Robotropolis to shut down the Robot Generator (which Dr. Robotnik gave instructions to destroy it). Knuckles destroyed them while Sonic and Tails kept going. This version of Snail Blaster was based on concept drawings and not its in-game graphics.
- In the original manual, they were called Snale Blaster. This was corrected in Sonic Jam.
- In the OVA, Snail Blasters could move up and down the walls in Robotropolis easily with wheels, while in Sonic the Hedgehog 3, these badniks slowly grovel.
- In Sonic Lost World, Snail Blasters are able to turn into tolling wheels in order to move faster.
