This Badnik prefers underground areas which are well suited for his unique talents. Be on the lookout as Burrobots have a habit of jumping out of the ground!

— Profile, Sonic the Hedgehog 4: Episode I website[1]

The Burrobot[2] (モグリン[3] Mogurin?) is an enemy that appears in the Sonic the Hedgehog series. It is mass-produced, mole-based Badnik model created by Dr. Eggman. Using their drill-like nose, they can launch surprise attacks from underground.


Burrobots are seemingly loosely based on European Mole. They have a blue body consisting of a round torso and a large head with round black eyes, gray disks for ear pieces and a large gray cone-shaped drill bit for a nose. On their head they wear a yellow hard hat. Their chest is gray, their shoulders are yellow and round, and their two arms are gray with three sharp fingers on each hand. As legs, they have tracked wheels on each side, which runs between two wheels; one is small and one is bigger.

Burrobots in Sonic the Hedgehog 4: Episode I are more detailed. The ear pieces have red bottom placed screws and their tracked feet have a elastic bands between their wheels. In Sonic Lost World, they wear yellow goggles while digging.

Game appearances

Sonic the Hedgehog (16-bit)


The first appearance of this Badnik was in Sonic the Hedgehog (16-bit), where it served as an enemy. This time around, this Badnik is referred to as Burrobot[2] (モグリン[3] Mogurin?). In this game, the player encounters them in Labyrinth Zone and Scrap Brain Zone Act 3.

In gameplay, Burrobots appear either alone or in groups, usually hiding beneath the floor and waiting to pop out to attack Sonic when he gets close to them. Their noses can be seen poking out of the ground so it is easy to spot where they will pop out of to attack the player. Othereise, they roll slowly along the ground and can climb up higher ledges almost instantaneously. As they jump out of the ground, the player can use a well-timed Spin Jump to defeat them, when they roll along the floor, they can be taken out with a Spin Attack. Also, upon their defeat, they release an Animal and reward the player with 100 points.

Sonic the Hedgehog (8-bit)

In Sonic the Hedgehog (8-bit), Burrobots appear as enemies, but only in Labyrinth Zone. Otherwise, they have the same attack pattern as their 16-bit counterparts; they jump out of the floor when Sonic approaches, roll slowly along the ground, and can climb higher ledges in an instant. However, Burrobots, along with the other Badniks in the game, do not have Animals inside of them. Regardless, upon their destruction, they reward the player with 100 points.

Sonic the Hedgehog 4: Episode I

In Sonic the Hedgehog 4: Episode I, the Burrobots returned as enemies. In this, they received a more modernized design. In this game, this Badnik is referred to as the Burrobot[1] (モグリン[4] Mogurin?),. They are only encountered in Lost Labyrinth Zone.

In gameplay, the Burrobots behave much like they did in the original Sonic the Hedgehog: they pop out of the ground when the playable character approaches, and when on the ground, they move along it slowly. They can also climb up onto higher ledges in a near instant. Regardless, they are destroyed when hit once by any of the playable characters' attacks. Also, upon their destruction, they release an Animal and reward the player with 100 points.

Sonic Lost World

In the Wii U version and PC version of Sonic Lost World, Burrowbots have their original design. During the game, it turns out that the Badniks, including the Burrobots, got hijacked by the Deadly Six.

In this game, Burrobots appear in the wide-spaced sections of Frozen Factory Zone 1, waiting for Sonic to approach. When they pop out of the ground to attack the player, they often end up getting stuck in the ground with their drill nose. The Burrobots also appear in the underground section of Silent Forest Zone 4 where they will chase the player while they are using the Yellow Drill. However again, this Badnik can get stuck on floating stone circles should it collide with it. The player can defeat it by ramming into its non-drill spots with the Yellow Drill.

Mario & Sonic at the Rio 2016 Olympic Games

In the Nintendo 3DS version of Mario & Sonic at the Rio 2016 Olympic Games, Burrobots make a cameo appearance as walls during the Golf Plus event on Hole 9, where they use their sprite appearance from the original Sonic the Hedgehog. If the playable character's golf ball hits a Burrobot wall here, it will disappear and the golf ball itself will land safely on the lawn without falling onto unfavorable terrain.

Powers and abilities

Burrobots are equipped with nose-based drills that allow them to burrow through the ground. This enables them to launch surprise attacks from below by emerging in front of their opponents from the underground.

In the Sonic the Comic series and its spin-offs published by Fleetway Editions, the Burrobots appear as the first generation of Badniks in Dr. Robotnik's army. Because of the different artists, the Burrobots would have different looks between the stories. However, as Robotnik would design new Badnik models for digging, the Burrobots would be replaced by newer robot models. One time, Shorty the Squirrel's friend Hopper was even turned into a Burrobot until he was freed by Shorty when he turned against Robotnik. Also, Tails disguised himself as a Burrobot on one occasion.

  • In both the 16-bit and 8-bit version of Sonic the Hedgehog, some of the Burrobot's exterior armor is shown to be red, instead of yellow as shown in the artwork due to palette issues. The upgraded appearance of the Burrobots in Sonic the Hedgehog 4: Episode I uses artwork colors with detailed mechanic parts being colored red.
  • A Burrobot-like Badnik was considered to be enemy for scrapped R2 of Sonic the Hedgehog CD, but the enemy was not included in the final release.
  • The Burrobots' attack pattern in Silent Forest is a reference to a stock artwork from their debut game.
