The Crab Excavator is a miniboss that appears in Sonic Boom: Rise of Lyric. It is an ancient giant robot located in The Pit which were used for Lyric the Last Ancient's digging operations there.


The Crab Excavator is a massive red robot at the size of a building. Its design is reminiscent of both a crab and a spider, possessing a large round torso with layers of armor which reveal grey clock mechanics between the cracks, several back pistons with red lines on top of its back, a fin down its spine, exhaust pipes on the sides, a semicircle for a head with only two red eyes for features, and four massive legs with hand-like feet with three digits each. On its belly it has three oblong black drills with pink spikes which can swirl as well as rotate together.


When the Crab Excavator broke down, it was left to be used for scrap metal by Lyric when he resumed his operations in The Pit. As it was being dismantled by the Destruction Troops, Sonic and Knuckles and smashed the robots. Opting to proceed through the Crab Excavator, Sonic and Knuckles reactivated it to get by it, only for the massive robot to attack them. Regardless, the Crab Excavator met its end at Sonic and Knuckles' hands, who used the hole it made to enter the tunnels.

Powers and abilities

The Crab Excavator possesses a powerful multi-drill on its belly which can quickly drill through rocky ground and crunch up Destruction Troops instantly.


The Crab Excavator is the first miniboss of Sonic Boom: Rise of Lyric and is fought with Sonic and Knuckles in The Pit on top of the cliff right before the tunnel passage segment. To begin the battle, the player has to tear off its faceplate with the Enerbeam.

Boss Guide

During the whole battle, the Crab Excavator remains in one spot while its drill rotates right below it. The Crab Excavator is invulnerable to the player's attack and touching its drill will inflict damage. While the Crab Excavator does not attack itself, Destruction Troops like the Shocker, Swordsman Trooper, Gunslinger Trooper and Blaster Trooper will swarm in the area in an endless stream.

To defeat the Crab Excavator, the player has to grab the smaller enemies with the Enerbeam and throw them into the Crab Excavator's drill which will destroy the enemy and damage the boss. After throwing six enemies into it, the Crab Excavator will be beaten and the player can proceed through the hole below it.
