I worked on drawing the Rat dragon when the last Creator Dragon announced its winners, now im finally making an entire. Hope yall enjoy. 

Species: Rat Dragon 

Element: Dark 

Type: Rodent Dragon

Average Body Height: 1.5m to 2m

Average Body Weight: 250kg to 330kg

Egg Stage ⬇️

Egg: This Egg appears to be made of thick and carefully placed nesting materials to insure the safety of what lies inside.

Hatch Stage ⬇️

Hatch: Freshly out of the egg they appear to be bald, bright pink and blind, they probably can't do much on their own.

Hatchling Stage ⬇️

Hatchling: At this age they appears to have gain fur, eye sight and a new found curiosity for everything. 

Adult Stage ⬇️

Adult: Rat Dragons are most active at night but aren't afraid of coming out during the day to seek some type of adventure. 

Since Rats can have many different patterns and fur colors I've made a breeding chart concept.

Partly inspire by the Lizard dragons and there multiple forms.
