when mysterious packages (new sandals, new animal skins, etc.) keep arriving at cave door for mrs. grug, grug not save very many shiny rock. also, wolves and sabretooth tigers get hungry, need grooming, need vet, etc. picky about food too, want expensive organic stuff. sometimes mrs. grug buy animal skins for wolves even though they have perfectly fine pelts of their own. and don't get grug started on lil' gruglets (which this grug not have). then no pile of shiny rock for rainy day, when shiny rock stop coming and cave mortgage is due. shiny rock very important. get as much shiny rock as can without compromising values. happy mrs. grug = happy grug.
