This is more a species entry than character entry - plus still refining these guys, so might list down what I have in dot points for now :D
This is an open species! But please link me to your character/design :D I want to see what people come up with!
Wings are actually covered in a light transparent fur, that acts almost like fibre optics. Noodle Dragons can pump blood to their wings to make their markings show up for display.
The number of legs indicates how old a Noodle Dragon is. They are born with 5 sets of legs and grow another set as they lengthen roughly every 100 years.
Their arms/legs are identical, so both hind and front legs are useful for speech, crafting etc
Noodle Dragons communicate mostly with an incredibly complex sign language - the most basic of the language uses two arms, while majority of it uses 4 arms and sometimes even up to 6.
"Mask" markings are unique to every Dragon, even if they appear to the human eye to be identical.
The ears of Noodle Dragons are incredibly sensitive and and are used for picking up echolocation - their only ability to "see" despite being adept at picking out colours.
