Someone can probably correct me on this...or at least correct/clarify some of my details. But the Giant Space Hamster harkens back to the Spelljammer Days of 2nd edition.
They were guardians, created in mystic laboratories all over the Spelljammer cosmos. They had these HUGE, TERRIBLE, FEARSOME stat blocks...and a morale of 3.
If you just looked at them funny and went, "AHHHH" they would run for their lives. Back those suckers into a corner though...and the FIGHT IS ON BABY!
They really were just a joke...but they also became something of an industry "pet" at the time. Of course, also being fondly remembered in Baldur's Gate..."Go for the eyes Boo"
Someone mentioned them in another thread, just got me all nostalgic. I don't have access to the original stat blocks for them, so there is no way I could stat block one.
But man, they were fearsome critters.
