another #spelljammer has a crew of fox hengeyokai. while they save provisions by being in their tiny fox forms during flight, part of their cargo hold is full of dirt, just because they got bored during flight and, in their fox forms, they want to dig holes.
the merchant ship crewed by dog hengeyokai had the same arrangement, until they met some tinker gnomes who invented squeak toys for them, which are also distracting but take less cargo space. they have a budget item for squeak toys now.
