Actually its quite easy really. It’s pronounced PUZZ-AXE-A-MIX. I learned that from Cat just as I was saving his life (once again) on this far away and very dusty planet. Pzzsxamix was a Bryllium mining planet but it was also home to the evil Mr Snosrap who was not only avoiding paying his galactic taxes but was also smuggling radioactive substances. I soon put a stop to his dirty dealings.
And where was this planet? Well nowhere near Alpha Centauri, which was where mission control told us to go before turning left. Useless lot.
