Blechovicz Pack Exclusive -

First, I'll try to recall if there's a LEGO set called the Blechovicz Pack. A quick search in my mind: LEGO has various themed sets, but I don't remember a "Blechovicz" set. Maybe it's a misspelling? Perhaps they meant "Bleach" or another brand? Alternatively, could it be a third-party LEGO-compatible set? Or maybe a limited edition or exclusive release?
