Type Ibn supernovae (SNe) are thought to be the core-collapse explosions of massive stars whose ejecta interact with He-rich circumstellar material (CSM). For CSM-interacting SNe, they typically show a remarkable homogeneity in their lightcurves.       OGLE-2014-SN-131 had the longest rise-time ever observed for a Type Ibn SN, more than twice as long as the previous title-holder. It was also approximately three times as broad as the average Type Ibn SN. I will discuss the potential powering mechanisms and the progenitor nature of this shockingly peculiar circumstellar-interacting stripped-envelope SN, and compare it to other Type Ibn SNe. We believe the answer lies in the mass of the progenitor star. However, another conclusion is that more detailed modeling is needed to evaluate the progenitor and possible powering mechanism scenarios with observations. I will discuss how current efforts are lacking for answering these questions.
