Octobygg

Octobygg is an enemy the protagonist encounters in Coral Reef.

Appearance
It pretends to be a Octosmal, but once approached or attacked, it reveals itself as Octobygg. It can be identified before it transforms, as it is completely stationary and lacks animation in its Octosmal form. Another way to tell if it is a Octobygg is if it cannot be spared immediately.

Trivia

 * Octobygg does not make an appearance in New Home to tell the story of Asriel Dreemurr.
 * Moldbygg is one of the animal species making up the Giraffemate named Mango Juice; specifically, Mango Juice is spared by un-hugging, an ACT adopted specifically from Octobygg, and Mango Juice appears to have Octobygg's top-most tier segments as her teeth and several bumps from Octobygg's lower tiers.
 * Octobygg can only red-orange throughout the game.
