Teaser
The teaser trailer for Side Order features a slow pan across a dull, stark white version of Inkopolis Square from, focusing on an unknown Octoling character. The Octoling wears their hair in the Tentacurl hairstyle, their ink color is a faded brown, and they are dressed in a short-sleeved white jumpsuit with matching white knee-high boots. Throughout the trailer various cryptic static images and short clips briefly flicker on-screen; the images primarily depict the Octoling in strange bright white locations, as well as Off the Hook, while the clips seemingly depict neurons, eye floaters, a brain, and octopus tentacles. The ground appears to be coated in a thick layer of snow, and bits of snow-like specks can also be seen floating in the distance. Branches of presumed dead or bleached coral are present throughout the plaza. Deca Tower looks entirely different, resembling a normal building with various billboards affixed to it rather than a battle tower. The Great Zapfish is also absent from its resting spot. A swarm of fish swim towards the Octoling towards the end. A dull, slightly out-of-tune music box melody with steady electronic percussion accompanies the teaser, which slowly grows more intense; towards the end, Marina can be heard speaking.

Teaser images
Throughout the teaser trailer for the mode several cryptic static images flash on screen very briefly.

Trivia

 * Side Order marks the second DLC to feature a central Octoling character separate from the player character, as well as Off the Hook as supporting characters, the first having been.

Etymology
A side order is another term for a side dish, a food item meant to accompany a larger main item as part of a meal. The title is likely a pun on Team Order, a Splatfest team in that was represented by many Octolings, such as Marina.
