Blue Caterpillars/BBOs generated by Illustris?

In GZ3 etc I looked in some depth at a class objects which we designated BBOs or Blue Caterpillars. This object however is the first time that I have seen an Illustris object that really comes anywhere close. Does anyone know of any others?
The characteristics are a lack of structure (no bars, spirals etc etc) with a diffuse, nebulous background and two or more blue nuclei (generally three to five). AGZ0008bj5 is pretty archetypal.
Look forward to hearing about any examples you come across.
