@FoxBat this takes me back, she's a part of a sibling pair. Both are the sweetest snakes I have ever had the pleasure of working with and are very patient animals, especially with some of the lore boisterous guests.
Are you sure this is Rosie (the female)? She lacks one eye, for this reason she is not usually presented. Her brother Shiro is usually used for any interaction sessions, plus he is not as "pure white" as his sister.
