We present a model for the Type Ib SN 2008D, associated with the X-ray
Flash 080109, which assumes a double-peaked 56Ni
distribution. This assumption is fundamental to 
explain the plateau observed in the light curve a few days after the
explosion. The presence of this high-velocity 
radioactive material may be caused by the formation of jets during the 
explosion. We briefly discuss the alternative scenarios that have been 
suggested for this supernova.
