I heard about some episodes of the anime for Maeterlinck's Blue Bird being on Youtube a few years ago. I drew this using them as reference. I know Tylette is better known as Shanet in some places, and Tyrol as Tylo.

You can watch the episodes from here: https://www.youtube.com/playlist?list=PLBKHQ6i8TLtiut63e9DudOhf8BvhN8C91

The captions are Italian, though.
