Octopod

Octopods are pill-shaped Octarian enemies that appear in Octo Valley and explode into purple ink when close to the player.

Description
Octopods are small, mechanical Octarian contraptions with two large, purple eyes, a nozzle for a mouth, and two legs adorned with lavender sneakers. When undisturbed, Octopods are calm and meander slowly in various directions. However, when close to an Inkling, they become angry, jumping and hissing while charging at the supposed threat. When they are close enough to their target, they explode in a burst of purple ink. However, if Octopods are destroyed by an Inkling's ink before this occurs, they will instead explode in a burst of that ink.

According to the Octopod Mem cake unlocked by the player in the Octo Expansion, it is possible that Octopods may indeed be outfitted Octarians, based on the fact that the mem cake reflects Agent 8's own memories of the Octopod corps. and hints at his/her own remorse for the danger they are forced to put themselves in for the Octarian cause.
