Coiny

Although Coiny is nice sometimes, he is relatively rude most of the time. In addition, he occasionally has conflicts with others. The most notable of which is with Firey. During the first season, he had an intense hatred toward him when the two frequently slapped each other in episodes. This was because Coiny forgot about Firey's poison, water.

Coiny has also shown an ability of persuasion and charisma. He generally tries to give speeches toward the other contestants on several accounts throughout the series. He was even able to convince Firey to let him into Dream Island.

Coiny now has many more or less rude and abrasive moments than before with some of the contestants who aren't his friends, such as Teardrop, Bomby, and Spongy. He is also more of a leader and a strategist coming up with ideas to help his team and Pin. For example, he convinced her to switch teams and used his teammates' abilities to benefit them in certain challenges, and frequently checking on her well-being and trying to calm her down when she's upset, like when she’s frustrated by Ruby’s performance in "PointyPointyPointy ♫."

Additionally, in the same episode, Coiny expresses frustration when Pin is the target of jokes and takes action to support her, such as spinning the prize wheel on her behalf to ensure she receives a favorable outcome. This emphasizes Coiny's loyalty and protective nature, especially towards Pin. He works closely with her to complete the challenges, and his willingness to assist in fixing her mech suit shows his commitment to teamwork.

Coiny is shown to be somewhat childish and energetic. This is shown in "Welcome Back," where he yells that the Grotatoes will taste delicious and tries to eat them when they've barely began growing. He also hypes up the Wall Teleporter calling it his "favorite thing in the whole world" despite not knowing what it is. Finally, in the stinger ending of the episode, he gleefully takes "deep-fried breaths" with boiling frying oil, much to Fries' and Leafy's terror.

Coiny is nicer and also much more thoughtful. Some examples of this are shown when he comforts Pin in "Four Goes Too Far" and offers Marker some dirt cake in "This Episode Is About Basketball". He has also seemed to have grown closer to Firey over this time.

Coiny showcases his ability to think creatively and utilize the strengths of his teammates to achieve the team's goal, such as in "You Know Those Buttons Don't Do Anything, Right?," when Coiny uses Pin to climb the building. This also influences the strategy of the other team members, indicating that Coiny's actions can have a broader impact on the team.

He also seems strongly attached to how things used to be, particularly regarding his relationship with Pin during their time in BFDIA. In "The Worst Day of Black Hole's Life," when Pin expresses discomfort with using glue in this challenge and shares her dislike for that season, it disrupts Coiny’s perception of their dynamic, leaving him confused and questioning this unexpected side of Pin.
