Dungeon Petz: Bob the Blob Promo Pet
A promotional pet initially given with copies of the expansion Dark Alleys upon its launch at Essen Spiel 2013.
Unfortunately, the promo arrived to us without the plastic fastener. Our understanding is that there were some extra plastic fasteners included with the base game/expansion that were intended for these expansion promos. Our best suggestion is to contact the publisher to see if they have any spare fasteners.
