Firetin

Firetin is the slash ship between Firey and Gelatin from the Battle for Dream Island fandom.

Canon
Back In BFDIA, Firey and Gelatin had spent some time together usually playing games. They had become temporary friends, but in later seasons, they don't interact much.

Gelatin tells Firey to ignite Bomby.

The two are sitting on the Eiffel Tower along with Book and Tennis Ball.

Gelatin believed he was saving Firey when he killed Leafy, apparently so did Firey. Firey asks if it's time for Cake at Stake, Gelatin says it is but Pin stabbed the Puffball Speaker Box. Firey tells him not to worry since he still has his Firey Speaker Box.

Puffball reveals that Firey and Gelatin tied their legs together and fell off.

Firey and Gelatin tied their legs together in a very specific way and try to stand up, causing them to fall off of puffball.

Gelatin manages to fool Firey into believing he is actually Flower. They are later seen playing patty cake.

Gelatin almost bursts into tears when Firey calls him and his team the "Have Crybabies", and he helps his friends push Firey into the Sun.

Firey confesses that he burned the high speed train, and Gelatin says that it's "not okay" and they have to walk to Yellow Face's Warehouse. After Lollipop says they can ride the 200 year old steam train, Firey says, "Yeah Gelatin, go ride that!".

Gelatin asks Firey how his party is going, who responds he wants to make a gift for Leafy. Gelatin offers helping Firey with his gift, and Firey thanks him.
