This particular subspecies of Aubrey, dubbed the Yanbergine for it's unusual hunting method of Sunny's and adjacent varieties. She will locate a Snuuy that has recently lost it's Mari figure, and slowly ingratiate itself to the brokenhearted Sunny. If done properly, the Sunny will go through its usual process of re-imprinting on the Yanbrey as if she were a new Mari.
Once the process is complete, the Sunny will undergo fairly similar development to a Mari-lost Sunny until stagnating at the regular naps stage. The Yanbrey will continue to provide for and predate on the Sunny as it becomes dependent on any form of love and attention received. The Sunny will spend most of it's life sleeping or providing the Yanbrey with what she wants; wants which ranges from cuddling, listening partner, bedwarmer, mating, etc. The Yanbrey is incredibly territorial when it comes to her respective Sunny, often finding homes where the Sunny can be kept away from any other living being. The Sunny's instincts at this stage encourages it into obedience and will almost never wander or seek out others.
While initial estimations of this relationship deem it as undoubtably parasitic, scientists have noted that it's unusual for Sunny's to live past the initial Mari-lost stages without assistance. When introduced to a Yanbrey, the survival rate skyrockets to a staggering 90% which leaves mainly natural causes as a threat to its life. The idea of introducing Sunny's to a relevant Yanbrey was initially suggested for conservationist efforts, but seems unlikely for serious consideration with how drastically this affects the development and growth of a Sunny.
It is currently believed this sudden and significant change in the garden variety Aubergine's behavior is due to the change in her bow. The usual bow of blue color has faded to a dull white color, reflected in the irises becoming much paler in color. Research is still pending on the true effects this change has on the Aubrey's development.
