— Profile, Sonic the Hedgehog 4: Episode I website

The Burrobot[1] (モグリン[2] Mogurin?) is a recurring enemy in the Sonic the Hedgehog series. They are mole-based Badnik models created by Dr. Eggman which first appeared in Sonic the Hedgehog (1991). Using their drill-like nose, they 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 the original 16-bit version of Sonic the Hedgehog, where it served as an enemy. This time around, this Badnik is referred to as Burrobot[1] (モグリン[2] 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. 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. As they jump out of the ground, the player can use a well-timed Spin Jump to defeat them. ALso, upon their defeat, they release an Animal.

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. However, Burrobots, along with the other Badniks, do not have Animals inside of them.

In Sonic the Hedgehog 4: Episode I, Burrowbots are found in Lost Labyrinth Zone. Despite having an upgraded design, they have the same attack pattern from their first appearance.

Sonic Lost World

In the Wii U/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.

Sonic Mania

In Sonic Mania, several Burrobots make a cameo appearance in a trash heap in Flying Battery Zone.

Powers and abilities

Burrobots uses their nose-based drills to burrow through the ground. There, they remain hidden beneath the enemies' feet, waiting until the enemy is close enough. Burrobots then attack to from underground with their noses facing upwards.

Sonic the Hedgehog Story Comic

Burrobot appears briefly in Sonic the Hedgehog Story Comic manga. At the beginning of the Sonic the Hedgehog Story Comic Volume 3 story Sonic Rampage!!, Burrobot and Moto Bug were sent by Dr. Eggman to beat down Sonic, but despite the their fierce nature, they got easily defeated.

Sonic the Comic

Burrobots also frequently appeared in early issues of Fleetway's Sonic the Comic, as members of Doctor Robotnik's Badnik army. Because of different artists, Burrobots have different looks in the stories. However as Robotnik has designed new digging Badnik models, Burrobots mostly have been replaced. At one time Shorty the Squirrel's friend Hopper actually turned into a Burrobot until he was freed soon after when Shorty turned against Robotnik. Also at one time Tails disguised himself as a Burrobot.

  • Mogura is Japanese for mole while moguri means diver.
  • In both 16-bit and 8-bit versions 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 Burrobot in Sonic the Hedgehog 4 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 Burrobot's attack pattern in Silent Forest is a reference to a stock artwork from its debut game.
