Hi - I noticed a couple of coloured spots on Pascal that stand out. I'm not sure if they're normal for most dragons, are part of a unique feature for him, or are a symptom of other issues.
Here are two pictures - one is on the tip of the tongue, and one is under his eye.
That is totally normal! All beardies have that. If you are referring to the purplish spot under the eye, that is actually just the eye because you can kind of see the the bottom eye lid. Nothing to worry about.
