The Snail Blaster, formerly known as the Snale Blaster (スネイル・ブラスター,Suneiruburasutā?), and later known in Japan as Den Den (デンデン,Denden?), is a snail-type Badnik model created by Dr. Eggman. The Snale Blasters made their first appearance in Sonic the Hedgehog 3. These badniks have a grey head and green and a red colored shell which includes two laser blasters inside of it.
Sonic the Hedgehog 3
In Sonic the Hedgehog 3, Snale Blasters will stick to the walls in the 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 a 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 to a certain point, it stops and shoots two energy projectiles towards Sonic. The player is able to destroy them easily by performing an unnamed kick attack. In 2.5D format acts, Snale Blasters aren't usually seen 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 the badniks, Snale Blasters included, got hijacked by the Deadly Six. Snail Blasters and Buzz Bombers are seen to be first badniks to turn against the doctor and attack him under the Deadly Six's orders. A few of them get destroyed by Sonic, but the predominance of Badniks and the Deadly Six forces Sonic, Tails, Eggman, Orbot and Cubot to retreat.
In Sonic Runners, the Snail Blaster is one of the enemies encountered in the game's stages. In this game, they retain their design from Sonic Lost World. Like the other enemies in the game, they come in their regular variant, a gold variant that grants extra points when destroyed and a dark grey variant that can only be destroyed by Power Typecharacters.
Apperances in other media
Sonic the Hedgehog: The Movie
Snale 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). Knuckles destroyed them while Sonic and Tails kept going. This version of the Snale Blaster was based on concept drawings and not its in-game graphics.
Their name was once corrected to Snail Blaster in Sonic Jam.
In the OVA, Snale Blasters could move up and down the walls in Robotropolis easily with wheels, while in Sonic the Hedgehog 3, these badniks slowly grovel.
