SO as my first proper submission to this site I'm gonna provide my persona's ref with some info on his species down here. Whether or not you read all this is up to you but it's here if you need it.

Bubbline is a bubble drake, a species of drake that constantly generates bubbles that are ejected through the tail. These bubbles are generated by a special sac in front of the stomach that uses internal heat and a naturally generated bubble-soap like liquid to make these bubbles.

The chemicals used to make the bubbles result in a glow matching the skin of the bubble drake. These bubbles also have a natural smell that is unique to a drake's genetic line. These are the only two constants, as these bubbles can be almost any shape desired and almost anything the drake in question can drink. Upon drinking a liquid, it is adapted into their sacs and can be temporarily used as part of the soap. This is commonly used for things such as increasing the amount of a drink or storing a drink for later, but many have theorized that if combined with a liquid that has combat potential, bubble drakes could become the most versatile form of drake.

Their bubble sac is extremely elastic, but should it be overfilled their stomach will be used as a temporary storage point. Due to their constant internal heat bubble drakes are resistant to both temperature extremes, being both used to immense inner heat and said heat negating cold to some degree. Most use this ability for fashion, as bubble drakes live domestic, non-intrusive life styles, and aside from the occasional heat wave or mini-ice age, they can wear whatever they deem fashionable.

Bubble drakes usually have large arms and tails and similarly large bodies. It is currently unknown as to why this is, but it's theorized that their non-hostile nature has resulted in their defensive, nonthreatening builds. Most drakes simply use their strength for house tasks. Their colourations are usually blues and greens, but most other colors of the rainbow have been recorded. This colour variance has had researchers stumped for ages, but the most commonly accepted theory is that this range of colours is dependent on that of the other drakes around so assimilation into any drake society is possible. This is further evidenced by bubble drakes being born as a stark white before their colours grow in.

And that's all that I think pertains to Bubbline at the moment, if clear everything else off my plate I'll write and draw more about the bubble drakes, but for now this should be fine. If you read this you're a trooper.
