The Tunnelbot[1][2] (ガキーン[3] Gakīn?) is a character that appears in the Sonic the Hedgehog series. It is a robot created by Dr. Robotnik, who used it during the first part of the Angel Island incident.

Appearance

The Tunnelbot is a wide robot with two drills on top, used to dig through the ruins of Marble Garden Zone's temples. Drill engines are inside two orange covers with cyan lines on each. The robot itself (sitting in between the large drills) only has a flat head with a cyan-colored eye.

History

Sonic the Hedgehog 3 & Knuckles

In Sonic the Hedgehog 3, and its locked-on version Sonic the Hedgehog 3 & Knuckles, Dr. Robotnik deployed the Tunnelbot in order to interrupt Sonic and Tails' adventure in Marble Garden Zone and, hopefully, destroy them. However, the robot was destroyed by the heroes instead.

Some time later, a re-built Tunnelbot would attack Knuckles the Echidna while he was in Marble Garden Zone. Like before though, the robot was destroyed by the echidna.

Powers and abilities

The Tunnelbot is capable of flight thanks to two hidden rockets inside it. Also, using its drills, it can drill through Marble Garden Zone's stone temples.

Battle

The Tunnelbot appears as the sub-boss of Marble Garden Zone in Sonic the Hedgehog 3 and Sonic the Hedgehog 3 & Knuckles, as well as the fifth boss overall in these games. In Sonic the Hedgehog 3, it is battled with Sonic and/or Tails, while in Sonic the Hedgehog 3 & Knuckles, it can also be battled with Knuckles.

Boss guide

The Tunnelbot appears in several places of Marble Garden Zone Act 1. It will wait for the player to arrive and will then drill into the ceiling, sometimes causing changes in the terrain. The player can jump at the Tunnelbot to damage it, but it cannot be defeated in the short time that it is vulnerable to damage, and the damage dealt has no effect on the boss battle. The Tunnelbot can eventually be found after the player takes the first alternate pathway or lower pathway through the temple section of the act. It can later be found again in another temple section, if the player goes around the downward guiding Shuttle loop and jumps off the first seen long pillar to the left.

Once the player reaches the end of the act, the Tunnelbot will appear and immediately burrow into the ceiling. The battle takes place inside the temple, where rocks will fall from the ceiling to the ground, some of the rocks being spiky stalactites capable of hurting the player upon contact. However, if the player is equipped with a shield, the stalactites can be deflected. A few seconds later, the Tunnelbot itself will emerge downward from the ceiling, trying to injure the player. This is the good time to attack it. The Tunnelbot will eventually rise up again and use the same pattern again, dropping out from different places each time. After it has received six hits, the Tunnelbot will be destroyed. When the Goal Plate falls down, one Lightning Shield monitor can be pop up from the left-side mound while Super Ring and Flame Shield monitors pop up from the right-side mound.

In Sonic the Hedgehog 3 & Knuckles, Knuckles confronts the Tunnelbot occasionally in the Zone and at the end of first Act normally. However, as he has a low jumping height, the battle is more challenging, as upon exiting the ceiling the Tunnelbot will stop descending at a high position that is out of reach of Knuckles' jump (as opposed to moving all the way down to the ground in the battle with Sonic and/or Tails). As the Tunnelbot drills into the ceiling, a large, rotating spiked pillar will rise from the corner and start moving to the other side, which can indicate where Tunnelbot will exit out of after drilling in the ceiling. It can help Knuckles reach the Tunnelbot, but the player must look out for spikes on the pillar while it moves. Dealing six hits normally will destroy the robot.

Variants

Rock Drill

Main article: Rock Drill

A Rock Drill in Sonic Mania.

The Rock Drills are larger, more powerful variants of the Tunnelbot. Like the Tunnelbot, they usually appear to interrupt the player's adventure. They first appeared in Sonic & Knuckles.

Drillerdroid

The Drillerdroid is an ever larger, more powerful variant of the Tunnelbot. Unlike the Rock Drills and the Tunnelbot itself, it has a metallic armor that protects it against attacks. It is also able to target its enemy and deploy iron balls. It first appeared in Sonic Mania.

In other media

Sonic the Comic

In Sonic the Comic, Tunnelbots appeared following Dr. Robotnik's discovery of the Floating Island. However, they are standard members of his Badnik army, and there is no suggestion of their being any different from any other Badniks.

Tunnelbots first appeared as part of the force that attacked Sonic's Secret Underground Base, forcing the Freedom Fighters to abandon it.[4][5] A Tunnelbot later appeared in the service of Robotnik's minions, the Marxio Brothers, guarding the Carnival Night Zone. It was among several Badniks that the Marxios used to attack Knuckles the Echidna, but it was destroyed along with the others by Knuckles' powerful punch.[6]

Sonic Adventures

A Tunnebot makes small cameo appearance alongside other Badniks from Sonic the Hedgehog 3 in one panel of the French Sonic Adventures comic, as Robotnik is sending all units after Sonic and Tails.

Trivia

  • The Tunnelbot's fight is loosely similar to the Drill Eggman II's fight at Mystic Cave Zone in Sonic the Hedgehog 2, as both vehicles can drop spiky rocks from the ceilings.
  • The Tunnelbot is the only sub-boss featured in the US manual of Sonic the Hedgehog 3.
