So I was doing a bit of research into running a possible Spelljammer one-shot or campaign, and I came across this:
"[Giant Space] Hamsters are domesticated, used as both pets and livestock, and are also used to power gnome sidewheelers, an inefficient form of space ship that is powered by a series of gigantic hamster wheels."
"Characteristically, the tinker gnomes did not stop there, and continued to breed many forms of hamster, including the sabre-toothed giant space hamster, the carnivorous flying giant space hamster ("a regrettable if understandable line of inquiry"), the fire-breathing phase doppelganger giant space hamster, and the miniature giant space hamster (a dwarf variant, indistinguishable from ordinary hamsters)."
"The most infamous (and to gnomes, most feared) giant space hamster was 'Wooly Rupert,' the Tyrannohamstersaurus of Ill Omen."
This is among the most wonderfully preposterous things I have ever encountered, and I no longer understand why anybody would ever not play Spelljammer.
