Battle trios
Battle trios, or Throuples when romantically involved, are a common theme throughout Deltarune, but begin to be played for humor primarily from Chapter 3 onwards. The distinction between both is also often used to humorous effect.
Chapter 1
Kris, Susie and Ralsei form a battle trio from Chapter 1 and onward. The idea of 3 party members at a baseline is often played with, such as when Lancer or the Candy join the party, or Susie leaves.
Clover, while one entity, comprises 3 individual heads with distinct personalities, which could be considered a battle trio.
When Kris and Noelle catch up with Susie and Ralsei, she joins the group. Additionally, Berdly and Starwalker can join, but only for the one room.
Noelle does not join Kris, Susie, and Ralsei in combat while in the group, keeping their battle trio intact.
Chapter 3
Elnina and Lanino form a throuple with both Rouxls Kaard, and then the Original Starwalker if he was encountered in Chapter 1. During the Second board, Rouxls mentions that the Party are "not the only battle throuple in town", which invokes confusion and embarrassment from Susie and Ralsei. Rouxls expresses shock that the Party "are not a thinge" during the Rouxls battle as well.
Elnina and Lanino, after separating from Rouxls, mention that "the only third they need, is each other", signifying that they may think of themselves as still being a Throuple, even without Rouxls or Starwalker.

Chapter 5
Noelle joins Kris and Susie at the festival, prompting similar join text to when she does it in Chapter 4.
Elnina and Lanino appear in the Dojo alongside the Original Starwalker if he was encountered, with only "Throuples" being allowed entry. One of Clover's heads does not like Cap'n, which is ignored by the Dojo.
Cap'n complains about his trouble in having multiple partners, and talks about missing Sweet and K_K, his original trio. His romance related issues stem from Clover enjoying music in a 3/4 time signature.
Pirate Dojo is played in the Dojo, having a 3/4 time signature and being composed with triplets. This is likely due to the Dojo's new found fascination with trios.
The Trashy Trio is assembled, constituting a battle trio.
At the conclusion of the fight, the Mikes appear, and begin a fight with the Trio. Upon the utterance of the word "trio" by Cowboy Mike, Elnina and Lanino also appear, stating that if they are a throuple, they would have to stop them.
Flowery's boss fight has three different trios, him with three pairs of the six flowers.

Bananas
Spinning banana
The banana, and the concept of potassium in general, appear in Chapters 2, 3, and 4.
Chapter 2
When Kris, Noelle and Queen are driving in the latter's car in Cyber City, a banana appears midway through the drive. Queen requests Kris to grab it, and if they do, she simply states "Potassium". If they do not grab it, she believes they will get sick,[3] presumably due to potassium deficiency.
The potassium gag is mentioned near the end of the Cyber City drive in Queen's car; Queen worries that "Poor Noelle [Will Clip] Into A Wall Somewhere", and "[Waste] Away From Potassium Deficiency".
Queen instructs Kris to grab the banana in her mansion
In the Acid Tunnel of Love, Queen once again requests Kris to grab a banana. Ralsei asserts they will not grab it, as they will not listen to her, but if they do, he states it is "good for [them]". If it is avoided, Queen says she wanted them to not grab it, so they become potassium deficient.[4]
Chapter 3
A banana appears in Shuttah's mouth in one of its ACTs.
The word "BANANA" appears alone in one of the quiz questions in TV World.
The same question may also use "BANANABABABA", which contains "BANANA".
