Wow! We just watched our little guy shed for the first time (we've had him about 3 weeks also), and while our change wasn't as dramatic, it sure is a cool experience! Your little one is showing some great colors!
This guy is a hybrid Sire is from Kammers hybrid lineage mixed with an Ambilobe female - his mix is pretty diverse and includes Ambilobe, Ambanja, Nosey Be, Tamatave, and Maroansetra. Can't wait to see if he carries the blue bars on a mixed red background like his sire.
As for the yellow in his mouth- that is completely 100% real - I did nothing in so far as adding color or altering the pics - that is just crazy genetics at work, and I love it!!
