Do you remember any of Hue's powers or any facts about the flames on his chest? If not, I change the question, are your main children afraid of something or do they celebrate Halloween?
Only a little,, since hes really small he wouldn't have any sort of power developed until much more later in life so hes pretty much normal aside from the little add-on's he has,,, This isn't technically a power but for facts about the thing on his chest- the color of his eyes and the tops of the flames on his chest would change with his emotions,, Since hes very small however, he wouldn't have as many complex emotions so it would only be a select few colors to mean multiple emotions until he gets older and they get their own color ( red is neutral (his default) / angry , blue is sad / confidence , yellow is happy / surprised, green is disgust / jealousy , orange is embarrassed / fear, etc) I forget what its called but the black stuff that drips from his eye and the pattern on his chest will not leave a trail,, it will actually burn off before it hits the floor and will (usually) not stain clothing
